never once used my phone either.

arguably, I don't want to. I have a credit card, I have cash. I have no reason to use a phone esp. in a situation where I have people literally waiting on me.

why do I tip these people if I have to do it all myself? might as well just order at the counter using my phone

You don't have to tip.

Believe it or not, most servers/staff at restaurants that do QR code and self-bussing don't care if you tip.
