Service industries. It's pretty simple. Any job where the worker is unlikely to be appreciated by their boss for going above and beyond but it makes a big difference to me.
The guy/girl says "i'm gonna be your waiter tonight", and that's the last time you see them, others bring the dishes and clean the table. And by law, they cannot share the tip.
When I pay for service, I'd like the employer and the market to figure out for me what's a fair wage. Don't put it on me, 1) I'll most likely be wrong and unfair, and 2) I just cannot tip the cook.
The cooks all made more money. Front of house people made like $2.25/hr (mid 90s), the line cooks made $12.
That's absolutely not true.
Looks like the front of the house can pool their tips in many states in the USA indeed. But according to Nolo, they cannot pool with people who typically get no tips.
"Only employees who regularly receive tips can be part of the pool. Employees can't be required to share their tips with employees who don't usually receive their own tips, like dishwashers or cooks."

A bunch of others expand with a communal tip jar, but it's very rare for anyone to care about putting something in the jar. You don't tip cafe workers, convenience store workers, retail workers and so on even though they get paid the same minimum wage.
