I waited on a celebrity at work

I'm a cashier and a few days ago I waited on the guy who played Kramer on Seinfeld. I've never seen the show myself, and he had a huge straw hat on and wouldn't speak to anyone. I had to show him how to use the credit card machine and he wasn't at all friendly. He was with a very snotty middle aged blonde headed lady. After they left, everyone came running up to me telling me who he was.
Anyone else waited on a celebrity at your work? Over the years I have waited on Pauly Shore, Diana Ross, Steve Harvey, a lot of professional wrestlers, basketball and football players, etc.
