I worked at restaurants through college, ~20 years ago. initially chains (og, bj's, etc) and later on some nice hotel gigs (fanciest having a private dining room that went for $10k/night). While today I'm less certain on tips, at the time I was 100% in favor. It was clearly beneficial. Other people i knew in college were making $8/hr working as security guards, or folding clothes in a mall and i was walking out of the hotel with $200+ in cash after a 6 hour dinner shift, and $100+ for a 4 hour weekend breakfast. This was not barely above minimum wage.
