Rihanna did something really cool for a waiter in LA the other night.

Rihanna shocked a waiter by leaving a $200 tip over the weekend.

The singer enjoyed a night out with six friends at the Laugh Factory Comedy Club in Los Angeles on Friday. Dane Cook was performing a stand-up routine and the group spent the evening laughing and chatting as they watched his show. Rihanna clearly had a great time, because when it came to settling the bill she offered a generous sum of money to the male waiter who had been looking after her table all night.

According to TMZ, the bill came to just $80. Rihanna apparently asked the waiter what the biggest tip he had ever received was, and he replied $100. The 24-year-old star then counted $200 into the man’s hand and told him, “Now I’m your biggest tip.”
