Potty Attack

I used to work in a large coffee shop in California. We were told not to let this one man into the store. This is why:
When this particular gentleman would get past the person working the counter, he would dive into the bathroom, alleviate himself fully, take his underpants off, and flush them down the toilet. This then would cause the toilet to backup and overflow. He would then joyfully skip out of the store. Who ever let him through the door would be in charge of cleaning up his fiesta.
