You work at a convenience store and you get the night shift Strange things often happen at night,the doors opening by themselves, CCTV errors, things falling off shelves and you ignore it because you think it's just mice

It was a rainy night, it was very quiet until the lights flickered and you saw someone at the cashier's desk and you thought they were regular customers until you saw their feet flying, your heart almost jumping out of your chest until they burst into giggles
