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'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 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". With the folks behind him in line      laughing hysterically, the man glared at the United Airlines agent, gritted      his teeth, and said, "_____ You!" Without flinching, she smiled and      said, "I'm sorry sir, you'll have to get in line for that,      too."
