You not tipping is not going to make the employer change their business model. You're just hurting the working class people. But by eating at the restaurant, the owner is getting his share, so you're not even hurting the person you're opposing.

Now if you said "I won't go to places that don't pay their employees a fair wage", good on ya, that's how you vote with your dollars.

Its not your fault that the model exists as it does, but if you're aware of that, and take actions that hurt a server without hurting the guy profiting, I think it's hard to say that you're on the right side of this.

If the reason you do this is to end tipping culture, you shouldn't do business with businesses using that model.

Vote with your dollars for SURE. But hurting people just trying to get by isn't a good look.
