McDonald's will stop testing AI to take drive-thru orders, for now

    PSA: Use the McDonald's mobile app, and always check the 'Deals' section before you order. On average you'll probably save 15%. Sometimes with a BOGOF, at other times with a discounted item.

    You can still use the drive through if you like. Just mention your order code instead of telling them your whole order.

      PSA: don't install apps for fast food places on your phones. That app collects huge amounts of data about you and they're profiling users including their "preferences, characteristics, psychological trends, predispositions, behavior, attitudes, intelligence, abilities, or aptitudes." It continuously tracks your location even when you aren't using the app or haven't used it in ages. They use your credit card info to track your purchase history/spending habits and they try to determine how much money you have.

      This seems like a great way to set prices according to how munch money they think you have or based on what you normally purchase. You might end up being charged more for the same items than they're charging the person who pulls in after you.

      No discount on their shitty food is worth the intimate details of your life. They sure aren't collecting all that information because they want to make less money off of you. Stop giving them the valuable information they need to take more of your money.

        "You might end up being charged more for the same items than they're charging the person who pulls in after you."

        That is exactly what happens if you don't use the app.

          Junk foods like McD’s slowly destroys your health.

          When possible avoid encouraging others to support companies like McD’s who are a net negative for the world. [0]

            If you only use the app how would you know? What happens when they take the menu board away and force you to use their app. How would you know then?

            Maybe you really are getting %15 off on your french fries today, but you'll pay for those fries again and again every time they (or someone else) uses the data they collected against you. That data never goes away. It'll be used against you for the rest of your life. They only collect it in the first place because they know that it'll let them take more of your money from you. What a short term/short sighted "deal".

            The OS won't let them track your location when you're not using it. They'll profile you based on your credit card info whether you use the app or not. And they need bulk data for psychological profiling, it doesn't make any difference whether you as an individual opt in or out.

            The mom-and-pop places that people who make a fuss about these kind of business practices tend to love do all the things that those people claim to hate - track their customers, try to figure out how much money they have, offer special treatment to particular customers, notice where else their customers spend their time - so I've never quite got what exactly people are objecting to. But hey, if you don't want the discount, more for me.

              > The OS won't let them track your location when you're not using it.

              I can't speak to IOS but it will on android devices (with some limitations https://developer.android.com/about/versions/oreo/background...) If you give an app permission to access nearby wifi devices it can track you that way as well. If you give an app permission to use bluetooth it can track your location using that too.

              > They'll profile you based on your credit card info whether you use the app or not.

              They might, but they'll have a lot less data to connect with your purchase history. You consent to a lot more data collection by installing their app than you do just by walking into their store and buying something,

              > The mom-and-pop places that people who make a fuss about these kind of business practices tend to love do all the things that those people claim to hate - track their customers, try to figure out how much money they have, offer special treatment to particular customers - so I've never quite got what exactly people are objecting to.

              No one wants to be tracked by mom-and-pop places either. All this data collection means that you aren't getting a discount, you're actually being screwed over and the data they collect will continue to be used against you for the rest of your life in any way that they think will let them take more of your money or would otherwise benefit them. They aren't collecting that data and paying for the collecting/storage/use of that data for your benefit.

              "Special treatment" doesn't mean what you think it does. This kind of surveillance leads to discriminatory pricing (see for example https://www.semanticscholar.org/paper/A-special-price-just-f... and wendy's recent attempt at surge pricing) which companies are desperate to get consumers to accept because it stands to make them much much richer at your expense. Don't fall for this! I promise that you won't feel like you're getting "special treatment" if they get their way.

            You save 15% but mcdonalds makes millions off all the data you consent to giving them by downloading the app. I also heard that, buried in the T&C of their mobile app, you basically consent to rescinding your ability to sue them? I'm not trying to pull too much of a gotcha though, I use the app myself.

              People always talk about apps "selling your data," and I can understand it in cases like Facebook (and Meta platforms in general) and Google, but in this case, how would it happen that McDonalds "makes millions off all the data you consent to giving them?"

              • autoexec 1 year ago
                The last I heard McDonalds said they aren't selling some of your data (like your credit card info or your location data) but that doesn't mean they can't sell other data, sell any of that data at some later date, or that the data won't get leaked or stolen and sold by someone else. Hasn't pretty much everyone gotten several data breach notifications by now?

                  a nicely packaged bundle containing the information of hundreds of millions of customers' travel/spending/lifestyle habits ... would allow a company to sell more shit to those consumers ... so that information is worth money .... especially when collected en masse ...
                • dartos 1 year ago
                  I don’t think terms and conditions ate powerful enough to prevent you from suing them.

                  That’s what the army of lawyers is for.

                • alphabettsy 1 year ago
                  I think a better recommendation would be to not eat at McDonald’s frequently enough to use the app or even have an account.

                • dangus 1 year ago
                  I would think that this is one of those LLM use cases that will definitely happen once McDonald’s finds a technology partner they like.

                  On the other hand, I also wonder if humans are too good at this task to make a big capital investment worth it. The employees who take your orders at McDonald’s aren’t standing around doing nothing, they’re wearing a headset and multitasking.

                    The cost of implementing this system vs paying a teenager minimum wage makes it not worth, and probably not worth it for a while. A lot of use cases for generative AI seem to miss that you can get humans to do them for pretty low costs and installing a new AI system is quite expensive and potentially error prone.

                      >The cost of implementing this system vs paying a teenager minimum wage makes it not worth

                      That's a math conclusion so lets show our work

                      Minimum wage is $16/hr in California + employee overheard so lets say $25/hr. With 3 people covering shifts at the drive thru, that's $219k per year.

                      Now for this system, lets look at off the shelf retail API prices to get a conservative guess. $0.006/min or $8.64 per 24 hours to listen & transcribe the customer, then add TTS + GPT-4o for $50 per million tokens in and out (thats way more than they need for a day). So that's $21k per year.

                      So back of the napkin math says it's 10x cheaper to implement this system. Unless you're referring to the corporate R&D budget.

                      • moose_man 1 year ago
                        I'm not sure I believe that math though. The person taking the order is also the person responsible for the drinks and the payment. Most of the inside is already done through app and kiosks. Drive through also has the ability to pick up app orders. The drive through order taking isn't the big cost here. You would still need that person to hand food, prep drinks. The real time is in prepping the order not taking the order. Reason for the line at the drive through is the meal prep not the ordering process. If AI slows down the ordering process in any way it is actually a net negative.

                          The part that you can get an AI to do, you can just as easily outsource to Indonesia or somewhere.

                              Exactly. A textbook example of using first principles for reasoning rather than just saying 'The cost of implementing this system vs paying a teenager minimum wage makes it not worth' - the equivalent of cavemen reasoning.
                            • dangus 1 year ago
                              Perhaps the worst thing that could happen is if the AI slows down customer throughput. If it saves money on labor but makes orders take longer that could be a big problem.

                                Also all the bad publicity / videos on social media hits their corporate image of competence so it's also damaging their brand.

                                Where are teenagers getting paid minimum wage for these jobs though? Where I live fast food jobs now start at $15/hr, not because of any laws, but because you simply can't really get anyone cheaper than that.

                                There have been tons of articles recently about how rising fast food prices are causing people to consider it a "luxury", and a huge part of those rising prices are rising wage costs. Where I live all the McDonald's now have kiosks inside for orders and fewer cashiers. I absolutely think shaving labor costs is something all fast food joints are interested in.

                                I do agree with the other comment that drive-through workers multitask (scooping fries, filling drinks, etc.), so I'm not sure how much savings you'll get just from order automation.

                                • moose_man 1 year ago
                                  The labor costs are not what's causing the price rises, the CEO have said so themselves on earnings calls. Also the costs of implementing the system at all restaurants when you have stuff like Kiosks already makes it overkill. They've already automated as much of the experience as is practical with AI's current limitations.
                                  • dangus 1 year ago
                                    Perhaps just a turn of phrase, as they are very close to minimum wage and some of the lowest paid jobs you can get.

                                    The point is that you can hire real live humans for not that much money.

                                    It becomes super valuable when the error rate is lower than humans though. I think this will be the main driver for applications like this.
                                    • moose_man 1 year ago
                                      Yeah, but from what I can tell, there are some fundamental issues to be solved before we get an error rate anything like that with Generative AI.

                                      It only makes sense to pay extra for AI if you scream “WE’RE USING AI” at the top of your lungs to investors, hoping they’ll throw more money at you.

                                    Was that not nationwide? I guess I had just assumed it was as all my local McDs have it.

                                    Seems to work just fine the few times I’ve tried it, but as a native speaker of US English without much of regional accent I’m not exactly a tough test.

                                      They are probably using 5+yr old STT model and then passing to an LLM. I think GPT4o's purpose is to solve this

                                          Is that more probable than using off-shore low-paid workers, like Carl’s Jr. and others (as mentioned in the article), or like the "Just Walk Out" technology at Amazon Fresh stores?
                                      • ivraatiems 1 year ago
                                        Carl's Jr was also piloting a similar technology. An AI took my order a few weeks ago, and mostly got it right (but didn't understand that I wanted "no sauce" with a certain item and gave me a side of sauce instead).

                                        I asked the real human at the window whether they liked the AI system. They said no, it made far too many mistakes. In fact, the company was going to be uninstalling it soon because it was wasting too much time.

                                        I can think of about a million reasons that might be, but one which particularly came to mind is that I live in an area where around 40% of people are Spanish speakers as their first language, and many of them speak no or very little English. The drive-thru employees would be completely capable of switching to Spanish (or summoning a Spanish-speaking employee) as needed, but according to the woman at the window, the AI couldn't do that. It also had issues with accents.

                                        None of that is unsolvable, but it's disappointing that it apparently wasn't even thought of.

                                          This is one of the things I don't get about the AI hype.

                                          Why does everyone want to use AI to _replace_ humans?[0] This sounds exactly like a case where an "AI" transcribing a human's order ALONGSIDE an actual human would be a perfect case for optimising.

                                          If the human mishears something for example, they can check what the AI interpreted, but still make their own decisions.

To be fair I live in an affordable housing project from the 1900s but yeah. AI would definitely beat shouting matches in the drive thru.
