9. Lea Michele
Lea Michele is best known for her starring role on the Fox show Glee. Unfortunately, she’s also known for being completely terrible to waiters in restaurants. Michele apparently harassed one of the servers who was waiting on her, and made fun of him when he tried to explain the ingredients in one of the dishes offered at the restaurant. She chastised the waiter, telling him he had no idea what he was talking about and complained about the waiter to several restaurant managers. During this incident, Lea was out with her family, and even sent her father to knock on the kitchen windows to ask when the food would be ready, even though she’d placed her order less than 20 minutes before. According to one of the waiters at the restaurant, the actress and her family were a real pain, and only tipped 10 percent.
