Cafe Robbery

The man hands over a five dollar bill. Slightly crumbled, you flatten it and put it away. You grab the correct change and begin to hand the change to the man. You look at the man as he hasn't grabbed the change. Your heart drops to your stomach, and you begin to sweat. The man is pointing a pistol right at your face. You can see right down the barrel, almost as if the bullet is at the other end waving. "Don't close that.", gesturing to the register with the firearm.
