I'm getting kind of old by tech standards (33), but when I was 16 (2007) I worked at a McDonalds franchise as a cashier, and their screens were TUI-based.
I actually really hated it, because there was a six character limit meaning that most stuff had to be abbreviated. A double cheeseburger was "DBLCHZ", McNuggets were "MCNUGS", Fillets of Fish were "FIOFIS". I got used to it eventually, but learning was a huge pain because you're at the whim of figuring the abbreviation of whomever programmed the machine.
Still, it's better than a lot of other fast food kiosks that I heard people use, where they didn't even have words, just pictures, which I think I'd hate even more.
I can't remember all of them, but the abbreviations sort of became a running joke amongst me and my coworkers; specifically we would use them for nicknames of managers we didn't like.
None of them were vulgar or anything, but for example we had taken to calling one of the managers "McNugs" because he stole a bunch of chicken nuggets (like literally a whole box, not just one or two from the line), tried to claim that the workers did it, and we actually needed to get the security footage to exonerate us, and surprisingly he wasn't fired for it. We all started calling him McNugs, which he absolutely hated, but I think he was afraid to do anything about it because he was already on thin ice for trying to frame us.
I might have them written down somewhere, I'll have to look.
