The so-called 'hidden caste system' that has tipped employees at the top of the F&B food chain, earning significantly more than back-of-house staff like bussers and chefs?
Yeah, exactly the same caste system. I didn't say only waiters were in a lower caste. This kind of bullshit is everywhere.
Some establishments pool the tips (cash ones) and use to distribute it to the bussers (don't know about the cooking staff). Obviously this was not a universal practice.
