My buddy was in an elevator with him.

My friend was staying in California for a vacation with his family and he was going up the elevator to his room and he noticed a man walk in with a nice outfit on. On closer inspection he saw that it was Christian Bale and then he asked, "Hey you're Christian Bale right? I love your movies." to this he replied in a snotty tone "Yeah I'm Christian Bale." Like my friend was asking the most stupid question he could possibly ask. He still isn't as bad as some celebrities, but he still could have a better attitude.
