I would not be at all comfortable, with a human server, making them wait while changing my selection multiple times (no I want it with the ginger sauce... no, without... no actually the sesame sauce... no actually I don't even want that dish, I'll take the other one), googling 10 different unusual ingredients while I make these changes, etc. And especially if I'm part of a larger party that shares food, or with kids, makes it all the more complicated. I just... am not ok with the social cost of it, even if a "good server" would be ok with it. (And who says you'll get a "good" one?). Whereas with digital ordering it's literally just zero-cost button clicks. And zero chance of error. I really don't see how it's even comparable, digital ordering is such a step forward. (Obviously not in all settings, like fancy dining, but for the mainstream).
