Last place I worked at that actually banned customers was at a pizza place in a college town that did a lot of late night deliveries back when restaurants delivered their own food.
Bounced checks, being rude to employees, not being there when the delivery driver arrived were the biggest ones. After hitting a critical mass on fraternities we started banning the whole fraternity if we ran into issues and they sorted that out fast by getting their members to behave better and other people would volunteer to buy the pizza if the person fell asleep or couldn't be found. Pretty much everyone who screwed up was given another chance by paying off their balance and the bounced check fee or apologizing to staff.
There was also one guy who never tipped and kept calling and saying is pizza was wrong so the owner made his pizza one night and delivered it himself, then banned the guy when he called and lied about the delivery. He was banned for life along with the people who were racist/sexist. The owner was a jerk when it came to his ridiculous capitalist expectations, but he did defend his employees from external assholes.
