«Tip-pooling» is common many places. This implies that tips is shared between employees, for example including the kitchen staff.
My single reference is the Norwegian upscale restaurant Theatercafeen, which introduced tip pooling across waiters and kitchen. It was highly contentious when introduced by the restaurant: The waiters took the case to the courts, and it went all the way to the supreme court of Norway [1], where it was decided that the employer could decide rules for tip-sharing.
