Or it just matches your own cultural preference.

I personally _hate_ American service with passion.

I prefer to be left alone most of the time in restaurants or not being talked to like the best friend I haven’t seen from the high school.

I also have an expectation that the waiter is not in a desperate position to rely on a tip for their living and is fairly compensated by their base salary.

No, it matches my experience.

My preference isn't necessarily for American-style service, that's just an assumption you'd be making with zero information.
