Ariana Grande
Ariana Grande became every retail worker’s worst nightmare in 2015 when she was caught on camera licking an unsold doughnut in a Californian store. To add insult to injury, the singer would also state, “I hate Americans. I hate America” upon seeing a batch of fresh doughnuts added to the mix – an apparently private moment caught on camera, and one which almost definitely didn’t win her any new fans.
