At a small restaurant with a hostess, might be somewhat straight forward, but wouldn’t call it easy to manage.
How is it going to work at high volume fast food restaurant with multiple entrances and kiosk ordering?
Honestly, many places like that just won’t care.
Will probably ask to see the app on a phone or whatever and then move on of the see it or not. It’s a dumb idea and I hope it will be short lived. NY doesn’t need it.
