Mystery Diners - Season 4 - Eps 8: Lactose Intolerant
The owner of Cheesie's Pub and Grill in Chicago, Illinois is concerned about cheating with his grilled-cheese-eating contest (too many petite women among the winners) and cost of his alcohol sales. The Mystery Diners point to bigger problems with his waiter and his cashier cheating to help the female contestants win and giving away free beverages. In spite of his waiter's pleas that it was good for Cheesie's during the confrontation, he and the cashier are fired. The narrator revealed that both former employees have apologized for their actions and moved on to other jobs. The owner has implemented new rules for his grilled cheese-eating contest to discourage cheating on both the customers' and staff's part.
