Yeah, I live in an area that straddles the line between the midwest and the south, and I haven't seen anything like this. Same for the QR-code-only menus that the internet has been complaining about lately.
I'm sure that if one local restaurant implemented this they wouldn't last long, but if a lot of local restaurants started doing it at the same time, they'd probably get away with it. Maybe they're all waiting for someone else to take the plunge.
