A man bursts into Mr. Lister's eatery insisting crayfish can be delicious and asks to cook. Lister and the staff refuse, mocking crayfish, so the man challenges the house chef and guarantees success—or he'll pay ten free-range chickens. The boss reluctantly allows him to cook two styles. Although the dishes look unpromising, the staff taste them and are stunned: the crayfish outshine the kitchen's signature fare and even the boss admits defeat. As applause follows, Mr. Chester steps in to propose cooperation, turning the culinary win into a sudden business choice.
