You are a hooters girl, no pantyhose please, really need to take a dump. However, you can't use the bathroom until closing. Customers complain about food coming cold and taking long time. One blame is girls taking long bathroom breaks, so I lock them up and can't use until closing. 
You beg to me to let you use it as you're prairie dogging the entire time, showing your butt clenched. You can only use it when we close up, so you have to hold it until that time. 

You show me your vagina and nice butt. 
Suddenly, you have an accident and humiliated by it, you yell at me that you quit due to it.
