One of my most difficult tasks as a flight attendant is to enforce rules while keeping customers happy. The electronic equipment that comes on board creates the greatest challenge. I walk the aisle asking passengers to turn off computers, electronic games and cell phones, which can create interference in communications between the pilot and the air traffic control tower.

During one landing, a man persistently kept his cell phone at his ear. I confronted him and said, "Sir, you cannot talk on your phone until we reach the gate."

"I am not talking," he replied. "I'm listening."
