There is a military bar at the base I work, and currently operated by coworkers until they can hire staff. Their PoS System automatically pops up the tip, and they have to tell us every time that they legally can't accept tips. So yeah, definitely default.
I can be a little sympathetic to the argument "this feature is built into our Point of Sale device, we didn't ask for it".
But 30/40/50% tip is not the default anywhere, that was done on purpose.
I can't. They are computers and they can be programmed however the restaurant wants. Any default other than zero is unethical and predatory.

Many restaurants I go to will tap the "no tip" button for you before letting you pay.
