Most of the food is for the staff
At least at the club we visited, the majority of the cooking feeds the folks working the floor.
The staff drinks heavily
This is true at many normal restaurants as well, but, in a strip club, the waitstaff is literally drinking with the clientele all day. This explains those broken plates, the long time before orders arrive, and why the servers might need an emergency order of French fries to soak up some of the gifts from their customers.
