My former boss, who made it through 30 years in the Marines and Army (Don't know why he switched) without messing up did it one day. He carried a crappy S&W Model 10 normally, but that day, he brought his old 1911, and somehow, he fired a round off. It put a ding in his desk, bounced off a breaker box, and then went through the wall into the ladies room, where the bullet ran out of gas, and barely touched a woman's foot when it dropped to the ground. He was about to go home, and was doing the same thing you were, as he was going to put it back into the case. He was very embarrassed, to put it mildly. The big boss just shook his head, and muttered. The woman that was in the restroom got a free stay at the hotel we worked at, along with free meals for the weekend.
