I think I'm in the smallest minority, but I haven't tipped in close to a decade. When people ask me why, I answer with the question "when was the last time you tipped your grocer l, fast food window attendant or the person at the hardware store that brought out your 100lbs of lumber? " answer is always never and I say exactly.
Are you going to like sit down restaurants in America though?... cuz those people make around $3 an hour most places with no benefits. I don't approve of the system but please don't go to a fine dining establishment and stiff the waiter. It's fucked up.
Not American. But even if I were, no I wouldn't tip. It's not my responsibility to pay someone's wage while the business opens up at another 2 locations in my city
