Tipping severs is the way our society works. By eating at table service restaurant you are implying that you are going to pay the server despite the fact that you have no intention to do so. It’s no different than your manager dicking you around by saying you’ll probably get a raise if you work overtime despite having no intention to do so.

Rationalize all you want, but you’re acting like a huge asshole.

If you are morally opposed to tipping, eat takeout or at a counter serve restaurant.
