A young second lieutenant at Fort Bragg discovered that he had no change when he was about to buy a soft drink from a vending machine. He flagged down a passing private and asked him, "Do you have change for a dollar?" The private said cheerfully, "I think so, let me take a look." The lieutenant drew himself up stiffly and said, "Soldier, that is no way to address an officer. We'll start all over again. Do you have change for a dollar?" The private came to attention, saluted smartly, and said, "No, sir!"
