Globe Magazine has reported that when Mariah Carey recently stayed at the Shore Club Hotel in South Beach, she ran up a huge bill of nearly $100,000, but the singer didn’t even leave a dime for a tip to a steamed staff. While a staffer says the singer was surprisingly pleasant during her stay, a waitress explained, “We usually don’t serve hot tea by the pool, but since she was so charming, I went and got it for her. But she left no gratuity at all. She’s a phony cheapskate-!” They suggest the singer bring her own teapot if she plans a visit again.
