My local burger place actually has them, but I think it’s a style choice. Like choosing a glass coke bottle instead of a can (although around here that’s because it’s “Mexican coca cola” which is significant better than regular coke, so maybe a bad example, haha).

I see them all the time. The only places I can think of that I haven’t seen them are places that use cloth napkins.

I mean I don’t go out to eat a lot either but presumably more than you (since you said you don’t eat out)
