All that will happen is people will develop scar tissue and just not tip anymore. People used to be polite and be nice when they picked up the phone from some number they didn't recognize. Scam artists USE this old custom to scam people. Well, most people don't even pick up the phone any more and for people that have to, like myself, the instant I recognize a cold call, I just hangup. I don't feel guilty about it anymore, in fact, I feel empowered.

Tipping at terminals is going to happen the same way. The idea that some minimum wage person is gonna recognize you, let alone still working at these places will key you in on this is just something that will go away.

Tip at a sitdown restaurant, that's normal. Tipping at a terminal for takeout, screw that.

I normally pay cash for food anyways as I don't want my eating habits data-mined for some future insurance penalty, etc.
