I was waiting to board a plane in Houston when a flight attendant stopped a woman in front of me to question her about the number of carry-on bags she had. The woman vehemently defended herself, claiming the extra bag was really her purse. It was the size of a large briefcase, but she insisted that it shouldn't count as a carry-on item. The flight attendant finally let the woman pass. As the next man stepped up, the flight attendant's gaze settled on his bags. Immediately, he held up his briefcase and exclaimed, "This is my wallet."
