Great story set at a fast food restaurant.
It's up there with the guy who started a fight in a McDonald's parking lot, died because he wouldn't give up, and then his parents sued McDonald's.
Other good stories include the impatient cop who pulled his gun on Dunkin Donuts, demanded the coffee NOW, and then didn't pay for it and the woman who (rightly) called 9-1-1 because a McDonald's took her money, said they were out of McNuggets and refused to give her money back. The insanity came from what she said to the operator. (I'm pretty sure all of this shit happened in Florida.)
