While at the high school one evening watching the basketball game, Nathan asked for money to buy himself a pop. Julie handed him a twenty dollar bill and he proceeded to find himself some pop.
He soon faced two options, buy pop from the vending machine or buy pop from the concession stand. He realized that it was a better deal to buy the pop out of the vending machine and proceeded to put his twenty dollars into the machine. He soon discovered that the vending machine wasn't going to accept a twenty dollar bill.
Meanwhile, the lady running the concession stand kept trying to convince him to buy pop from her. Growing frustrated Nathan returned back to his seat empty handed and exclaimed that the lady working the "concussion stand" wouldn't help him.
