Rihanna was at the Laugh Factory with friends just chilling. You know Valet cost her $100 Bills, she paid it, still got her money. But, when the check came and the bill was just $80 bucks, Ri Ri asked her waiter “what’s the biggest tip you have ever got?”. He replied, “$100″. She slipped the young lad  $200 and said, “Now, I’m your biggest tipper”. BO$$! Even though it wasn’t that much, on and $80 check that’s over 100% . I’m sure he was happy, but would have been happier if he would have said he was tipped more…. Besitos!
