Then don't go out to restaurants. Don't tip on bad service, but if you had good service, you not tipping is just you punishing the server for doing their job. They pay out to the kitchen and bar on every table, regardless if you tip, so when you don't tip, your server has to pay out of pocket to serve you. Don't care? Why don't you tell that server working 2 jobs to "just quit". You don't need to go out to eat. They do need to pay their bills. Stop patronizing an industry that exploits its workers, and then make it the worker's problems.
