Data has ruined fast food (among many other businesses).

When I was young it was common for a McDonalds to have 10+ employees working the lunch rush, one for every station and a few floaters cleaning the dining room. Someone took your order right away, and you got your meal in a minute or two.

Now I go and it's 3, sometimes 2 employees. You order on a tablet, and 10+ minutes later an overworked employee sets it on the counter and scurries away, probably after realizing it's not a drive-thru order. The dining room hasn't been cleaned since 6am, the trash cans are full. There's at least one alarm going off constantly.

Back then they were run based on someones intuition of what makes a good customer experience. Now they're run based on the data, and the data says they have enough loyal-to-a-fault customers like the author that chronically understaffing is more profitable than providing a good experience.

The problem with fast feedback loops is that they filter out long term signals. The problem with data driven decision making is that data is numeric, and the act of counting is necessarily an act of approximation, by which we erase the difference between objects or events in order to bucket them into a category so that they can be counted. So the kind of dashboards that modern managers demand, offer nothing but the most obvious, short term "insights", that you might as well eliminate the man in the middle and feed the data directly into a set of simple decision rules.

When I was young, they predicted orders and had hot food waiting, you would get your meal as you ordered. Unfortunately, after merciless teasing by other chains, they relented and only assemble to order and cook to order in some cases. Huge increase in lunch latency; ordering via the app can help a little...

The thing I most miss: Being hungry, going into McDonalds and seeing what they had on the shelf ready to eat now. Bic Mac, Quarter Pounder or maybe 2 Hamburgers.

Now? In the queue behind 23 other bespoke orders while they try and service the drive-thru as quickly as possible and nothing stopping them taking the burger that was made for me and adding it to another order.

I was so angry once, I walked out after paying and I just didn't wait for my breakfast muffin because the whole thing like the parent says is that they used to care about efficiency as well as customer experience and now that goes out the window.

If they are indeed saying understaffing doesn't matter because their current customers don't care, their loyalty numbers will only go up because of that sampling bias. Relatively upscale fast casual places (e.g. Chipotle) will fill replace McDonalds for the customers they lose. The circle of service industry life.

Different stores in different chains have a very different attitude. There is a Taco Bell in Ithaca which has a staff that has some esprit de corps and then another where the dining room is disgusting.

I've seen the same changes. The most noticeable is, now that they are no longer required to be visible at the front counter in case someone comes in to order, because of kiosks, the workers usually specifically hide anywhere else, to minimize the chances of being disturbed by customers with their endless requests ("I've been waiting for 15 minutes for a large fry...")

Don't underestimate the equally intense downward pressure on staffing that minimum-wage hikes have provided (for instance, in California). I won't speculate if it's been "worth it" since it'll devolve into an off-topic political debate, but basic economics does predict that since labor costs twice what it did 10 years ago, they'll do everything to minimize how much labor they buy. Couple that with what you said, basically, using "Moneyball" techniques to finesse everything with all these optimizations, we get the operations we see now in all retail establishments.

And even if there are states that haven't done the minimum wage changes, the markets that have are so big. The national businesses that have adapted to it have proven out their barebones-labor model there - why wouldn't they roll out most of the changes nationwide?

I think if someone launched a fast-food place or a drugstore in 1995 that operates with the type of skeleton crew they use today, it would fail overnight due to people having a choice. But today, since essentially 100% of retail operates this same way, they don't experience any pressure to do better.
