It happened at a New York airport.
A crowded United Airline flight was cancelled. A single agent was re-booking a long line of inconvenienced travellers. Suddenly, an angry passenger pushed his way to the desk. He slapped his ticket on the counter and said
"I HAVE to be on this flight and it HAS to be first class."
The agent replied "I'm sorry sir. I'll be happy to try to help you, but I've got to help these folks first, and then I'm sure we'll be able to work something out."
The passenger was unimpressed. He asked loudly, so that the other passengers behind him could hear -
"DO YOU HAVE ANY IDEA WHO I AM?"
Without hesitating, the agent smiled and grabbed her public address microphone. "May I have your attention please?" she began, her voice heard clearly throughout the terminal. "We have a passenger here at Gate 14 who does not know who he is. If anyone can help him with his identity, please come to Gate 14."
As the passengers behind laughed hysterically, the man gared at the United Airlines agent, gritted his teeth and said "F*** You!"
Without flinching, she smiled and said, "I'm sorry sir, you'll have to get in line for that too."
