I once heard a story about a traveler harassing a ticket agent at the gate of an airport terminal. The traveler didn’t want to wait to get on the plane so he went into a tirade. “Do you know who I am!” he shouted repeatedly at the poor woman handling the tickets. But the ticket agent handled him beautifully – she simply picked up the intercom and announced over the loudspeaker that this man needed help because he didn’t know who he was. Everyone at the gate laughed – especially those who witnessed his bad behavior.
