Cafes and sandwich shops with massively suboptimal choosing and ordering processes. Particularly ones where you can't tell what's on offer until you've actually got a member of staff looking at you expectantly waiting for you to order. There's one near us where you queue up with no sight of a menu at all until you arrive at the counter. You then move from right to left along the counter, but they take your order at the right hand end so that you don't see that really appetizing looking thing until you've already ordered and are waiting to pay, which you do at the left hand end. And then they put the tip jar back at the right hand end, so you're past it before you've got your money out. At which point someone's just walked in and sat down at the only spare seat in the place[1], so there's nowhere for you to sit, a problem that's exarcebated by the fact that it's fecking tiny and mostly taken up by people who've spent the last half hour ignoring an empty esspresso cup while doing something which we're clearly meant to infer is "creative" on their Macbooks. If the scacciata and spianata weren't so good I'd want to firebomb the place but annoying they are that good, is so I'm always inclined to put up with all the other irritations.
[1] at another place in town, I once saw the guy come out from behind the counter specifically to stop someone bagging a table until they'd queued up and got their order in, which impressed me.
