I worked as a waitress in a restaurant and there was a lot of customers. The chef had prepared a noodle soup that all waiters were giving to the cranky clients. When Rihanna showed up, she wanted to eat spaghetti. Since we didn't have any, I got her a soup bowl and she said, "thank you, shall I tip the waiters?". My answer was, "you know, tipping is not an obligation, but I think you should thank them... it would make them so happy!" Bottom line, Rihanna told me she wasn't too fond of Fifth Harmony.
