"Slammin" Cleon Salmon (Michael Clarke Duncan) is a former world heavyweight boxing champion who retired to open a sports-themed restaurant in Miami. His antics lead him to believe that he owes $20,000 to the head of the Japanese Yakuza. Needing to come up with the money in one night, he challenges the wait staff to sell more food than they have ever sold, with the top waiter receiving $10,000 in cash and the lowest waiter getting a "broken ribs sandwich" courtesy of the champ. Zany hijinks ensue as the staff try to one-up each other and win the prize while avoiding a beating. In the end, Cleon realizes that he only owed 20,000 Yen to the Japanese Yakuza (which works out to be $170) and shares the takings with the wait staff. But before he goes to give the Japanese Yakuza the money, he beats up Guy since he was the lowest selling waiter.
