I worked at a small convenience store in the early 1990's. They had one of those fry delis that had chicken, jojos, corndogs, burritos etc. This particular night I had run out of burritos and chicken. I also shut the thing down and cleaned it all out about an hour before closing.
About 5 minutes before I was closing up a guy walked in and asked for some burritos. I told him I was out of them, and that I was just about to close and the fryer was shut down. He walked around the store for a minute (I assumed he was looking for something else to buy) and then he came up to the counter, pulled out a knife and told me if I didn't cook him some burritos he was going to stab me.
I freaked out, but told him I had none to cook. I showed him the freezer and told him I would happily cook anything he wanted from it, but he will see I was out of burritos. He looked in it for a minute, turned to me and said, "You really are out." I replied, "Yeah." He then put the knife away and left the store.
