There you go. Dana got it right in fewer words.

eta: Question:

What would happen if management were to post (on the menu)
the way tips are distributed among the staff ?

Maybe tips would be more aligned with actual service,
quality of food, extra effort of service staff. etc.

I'd almost predict:
... some line cooks would walk away from job.
... some service staff would realize they are not getting equal shares
... some service staff would realize the owners are taking a share
... more customers would tip what in accordance with the meal and service
etc. etc.
