"Ticketless Travel"

My friend's brother, Cliff, is a very serious, dignified man, so his actions at an airport's check-in counter were totally unexpected.
     
It seems that he and his wife were placing their baggage on the conveyor when her purse accidentally fell onto the moving belt.  She scrambled after it but it eluded her, so she climbed onto the belt to try to reach it.
     
Just as she was about to disappear through the doorway with the baggage, Cliff began to wave frantically, "No, no dear!" he shouted.  "It's okay!  This time we bought tickets."
