The cashier who has to pee.

Sarah was about to go into a line up that was moving a lot faster than the one I was standing in. Then the cashier put a sign up saying that she would not take anyone. When Sarah joined me we watched the other line up and discovered the reason for that cashier’s productivity. She was jumping up and down and quickly swiping everything. She seemed to be closing her cash to go to the bathroom, but what a trooper for taking two extra shoppers before her break.
