You are simply wrong. It's trivially easy to disprove your several comments about SF tipping culture with a few google searches.

Don't confuse the fact that nobody has confronted you for the idea that waiters don't expect you to tip them.

If you're in places where non-tipping is expected and the staff are paid based on that, fine. If you're doing this in places where staff pay is determined based on expectation of tips, you may be an exemplar of what people hate about Silicon Valley dudebro culture.

It's entirely possible that restaurants in SF have shifted to non-tipping and jacked their prices up to pay higher base wages just because it's so expensive to live anywhere in that area, but in most of the country people in traditionally-tipped positions are often paid significantly below minimum wage (as low as $2.13/hour as the federal minimum, many states are higher). In California the tipped minimum wage at $11/hour is only $1/hour lower than the regular minimum wage, so not tipping may have less impact.

I for one wasn't aware of a no-tip culture in San Francisco. I would totally not do it provided I was absolutely sure that this culture was a thing.
