Not so far as I know, but mandatory tipping (i.e. adding a service charge to a bill) is illegal in many countries, and it wouldn't surprise me if having a tip screen on a payment terminal were against local regulations.

I don't think that's true. I will agree that it's not enforced enough, but the FTC and SEC do enforce laws on businesses on a pretty regular basis.
