I always tip 20% for anything better than terrible service. Because I won't be arsed with evaluating whether my server was "good" or "great" or "truly outstanding" or whatever. It's table service. I shouldn't have to think about it at all.

I would rather tip 20% than use mental bandwidth for that nonsense.

I tip 15% 2/3 of the time, 10% for the worst 1/6, and 20% for the best 1/6.

If you don't change what you tip in response to perceived service quality, there is less incentive to make an effort to provide good service. You're engaging in renegade behavior, just like anti-vaxxers relying on the herd immunity to protect themselves from their own decisions. As long as anybody has to play this stupid tipping game, everybody has to play it.

If you really don't want to worry about it, why don't you just refrain from tipping altogether? It's table service. The restaurant should be the one enforcing its quality standards, and not the customers, right?

Meh, I'll tip 20% if I want. I don't care what it incentivizes, at all. Thanks for the concern.
