When the owner of The Groves Bar & Grill becomes concerned over a large loss in food and supplies, the Mystery Diners go undercover with hidden cameras as new employees and customers, suspecting that a recently hired chef may be plotting more than just the items on the menu. During the sting, they reveal that the newly-hired chef is running his own catering business and using the restaurant's kitchen and supplies to run it, making business at The Groves suffer, with customers waiting extensively for their orders. The owner, as well as Charles, confronts the chef and fires him. The narrator revealed that the former chef has gone out of business without his own overhead. The owner has his food and supplies all in check, with The Groves having an improvement in business.
