Not what I expected at all

I had a friend from out of state swinging through town and we met in NYC for lunch and a couple of drinks. We are eating at the bar and I see further down that Mike Myers (Snl, Austin Powers, etc) is at the other end of the bar watching a soccer game on the television and drinking a beer. I had never encountered a celebrity before, and didn't want to be some obtrusive asshole. But prior to paying our tab I walked over and said "hey Mike, I'm a big fan, can I buy you a beer?" And without even turning to look at me he says " I can afford my own drinks asshole, save your money for my next movie". I stood there speechless for a second and embarassedly turned back to my spot at the bar, we paid our tab and split without saying a word. I really felt like a dick head, haha.
