So in some sense table service is an improvement. But I'm with the author on QR codes and mobile ordering. I'm sick to the back teeth of it. Every other restaurant or pub has their own flawed and busted-ass interpretation of how an ordering app should work, and payment is an inconsistent mess. Some places have an app, some have a website. None of it works the same bloody way, and it can all go and do one in the ninth circle of Hades as far as I'm concerned.
These are all first world problems, but they're still problems. And I'd take standing at the bar and ordering drinks over any of them, with possible exceptions for the busier scenarios I specifically picked out in my first paragraph.
(Don't overinterpret me: I don't mind sticking to the rules for the time being, but when restrictions relax and I don't have to do any of these annoying things any more I will literally skip for joy.)
