When I was (much) younger, I worked in a supermarket, and one day when I went up to the office for change for my cash register, two guys came into the store. One guy went up to the locked door of the office, the other guy pulled a very small gun from his pocket vest put it right up to my head, and said, "Open the door or I'll blow it off." I was hoping that he was talking about the door, but I knew better. Fortunately, the assistant manager did open the door and let the other guy in. They took their cash and fled. I was actually pretty calm during the entire thing, but was told by a police officer that I might have been in a state of shock at the time because when he brought a couple of us into the station to look at "mug shots", I was literally shaking.
