Thirty minutes after take-off the senior flight attendant announced over the intercom. “Ladies and gentlemen, due to a huge mistake by our catering company we will not have enough inflight meals for all passengers. The catering company only provided up with 40 meals and there are 103 souls on board today. I truly apologize for this error and inconvenience.”

When the passenger muttering died down, she continued. “Any passenger willing to forego their meal so another passenger can eat will be given unlimited free drinks for the remainder of the flight to compensate them for their generosity.

A hour later the flight attendant came back on the intercom and announced. “If anyone would like to change their minds, we still have 37 meals available.”
