Some customers at our restaurant (Boston, MA, USA) try to get a free meal by placing some hair in their food and then blaming the chef and refusing to pay for the meal.)

Customer: "Waiter!"

Me: "How can I help you, sir?"

Customer: "There's a hair in my food."

Me: "That isn't possible, unless it was your hair."

Customer: "It isn't!"

Me: "Who else's hair could it be?"

Customer: "Your chef's."

(I walk into the kitchen and return to the table with our chef.)

Me: "Take off your chef's hat."

(Chef takes off his hat, he is revealed to be bald.)

Chef, to the customer: "You were saying something about my hair being in your food?"
