This ignores how feast-and-famine tipping is; there's a high ceiling for potential earning, but it's not always a reliable income; and this also ignores how only those working in front-line service roles benefit.

Are you the kitchen hand washing dishes? Are you the chef or cook who makes the meals and food that the customers eat? Are you a cleaner mopping the floors after business hours? Nope - none of you get a tip, unless the restaurant has a policy of collecting all tips and redistributing them to all employees. But how often does that happen? It's really easy to just pocket the tip and keep it for yourself.
