I was at a gun shop recently when I saw the clerk hand a customer a gun off the shelf. Thankfully, I saw the customer inspect it, but he then pointed it down the aisle (straight at me) and pulled the trigger. I jumped over out of instinct right before he pulled, and he had a confused look on his face as to why I jumped over. He then chuckled and said "Hey, not loaded." I didn't know what to say. I just glared at him, bought my ammunition, and promptly left the shop.
