I stand corrected. I have not worked in food service for over 30 years so I can only presume the rules have changed, and not for the better. My current experience is from the other side of the table.
Bartender in college here. I get it too. Nowadays, you have to explicitly ask the resto’ of they include the tip. When we go out, we ask the place first if they do that or look at Yelp. IF in case, we all go hungry and just want to eat out impromptu, you do the same thing. But it’s not the dealbreaker. If the service and good are great, we don’t mind as the objective is to eat. No one really thinks of “oh man, I;m hungry but damn, they include the tip immediately in the bill”.
Not really correcting you per se, just giving you the latest info. Luckily we have yet to experience a restaurant that has added 18 - 25% to the bill just because they could. The only time we’ve had that experience was when we had a large group, except when we lived in Europe.
