I love and seek out restaurants that use online ordering and payment. I don’t need someone waiting on me. I’m in the US and they are not paid a living wage, the work is difficult with little reward. Now there is a place in my neighborhood where you sit down the QR code is table based, interaction is simple, clear and designed to work (uses Toast as the backend iirc). You order, the order stays open till you pay it’s a restaurant/bar so if you need another you don’t have to do anything but tap on your phone. They have amazing helpful servers that are paid well. You pay on your phone and leave when you are done. It’s amazing.

I think this is more about power dynamics than currency and menus. I think many people just want or more accurately demand that others (with less power) to serve them. I’ve even heard people say “it’s not my job to check me out or take my order.” Those same people treat their waitress like shit, when those waitresses are paid basically nothing to take the abuse. Then they try to weasel out of the bill. Seen it time and time again.

Now, some restaurants do poor a poor implementation of modern menus and it’s frustrating. However… long term those that do it well will win. It reduces friction and costs leading to lower prices higher margins and quicker more accurate service.
