Related to a thread in another board, someone was saying they have served in a restaurant where tip-out includes the kitchen staff. I've worked in about 20 restaurants, mostly national chains but a few indies and have never heard of this. Bussers, bartenders, barback, hosts/hostesses, yes. Even one place with "server assistants" who had to be tipped, but never the kitchen.
Have you had to tip out the kitchen? If so, what type of place was it (small indie? etc.)
