I knew a cabbie who thought like this. He would get pissy about a small tip. Same asshole refused to tip at restaurants because “I work hard for my money and not just going to give it to anyone. You gotta wow me.” nobody ever wowed him. In fact, he was one of the worst people I’ve ever seen in a public eatery. He would turn his plate over and dump the food on the table and act like a self satisfied 5 year old if his food wasn’t right. We’re specifically not friends because I let him know what I thought of that.

It’s not gratuity if it’s not a choice.
