Maybe that used to be the root of the problem but now the main issue is people make huge money off of tips in America. They expect 20% of all orders on prices which are already through the roof. They often take home many times their wages in tips. Then like many greedy people they start getting jealous of others who are getting even more than them and start demanding and whining about it.

Mr bean worrier here knows full well a guy in a small restaurant around the corner is getting those hundreds in tips while he is merely getting paid a living wage with training, benefits and paid holidays. He wants it all.
