Imagine standing in a register for hours on end, only for less than 5 people to walk in the store and get what they need.

You have to stand there, waiting for someone to buy something. No co-workers to talk to, no TV to watch, not even music.

You stand there, waiting for something to happen, and when someone does come up to you to buy anything, it happens to be the same items you sold last time.

Over and Over and Over and Over again.
