This happened at the Denver Airport...

...A crowded United Airlines flight was canceled. A single agent was
re-booking a long line of inconvenienced travelers. 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 am sorry, sir. I'll be happy to try to help you, but, I've
got to help these folks first, and I'm sure we'll be able to work something out."

The passenger was unimpressed. He asked loudly, so that the 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 find his identity, please come to Gate 14."

With the folks behind him in line laughing hysterically, the man glared at the United
agent, gritted his teeth and swore, "F*** You!".

Without flinching or "missing a beat", she smiled and said, "I'm sorry sir, you'll have to get in
line for that too."
