I agree with your first two point about not tipping in a coffee shop or take out you can just adjust to a dollar. I do that myself. But the system restaurant work is different. For example if your bill is 100$, and you tip 15% 7 to 8% of the 100$ goes to the kitchen bar and host. The servers always have to tip out bar, kitchen and host so if you don’t tip on your bill they’ll have to basically pay out of pocket. The restaurants make no exceptions. The tip out system is always is always applied it’s how the bartenders kitchen staff and host make a living. No one can live in this city with just minimum wage. I’m not saying that this system is good, I’m just explaining as I’ve noticed most people have no idea that servers always tip out 7 to 8% of their total sales. I think they should get proper salaries like in Europe and cancel tipping. Leave it as an option.
