Kitchen Staff - One Six Pack
That is one thing that always bugged me as a cook at restaurant in the early 1970s when I was in college. The "kitchen staff," the people who actually cooked the meals, made minimum wage period. No tips. While the waitresses made over $400 a night in tips, all the while taking breaks, and blaming the cooks for their mistakes (forgetting to turn in a ticket to the cooks, etc.) while the cooks worked non stop without a break. Sorry, had to get that off my chest.
I was also a cook for several years, but I made more than minimum wage.
