Mail Processing

During a hectic night of mail processing at the post office, a number of letters fell off an elevated conveyor belt and scattered onto the floor. Before the area supervisor had a chance to pick them up, the facility manager, who had a reputation for being stern, came upon the scene. "Why is this mail on the floor?" he demanded angrily. Without hesitation the supervisor replied, "Gravity, sir."
