13. Britney Spears
The famous Hollywood starlet, Britney Spears is one of the worst tippers. Once, she reportedly threw a small amount of change on the floor for a valet, saying to him, “There’s your tip.” If that wasn’t enough, she left a zilch tip, when she and her staff ate food worth $251 at One Sunset of Hollywood. She even once sent a waiter of Las Vegas to bring her a coffee from Starbucks, without even paying him for the drink, let alone the tip.
