I know tiger is so focus while playing a tournament, so focus, that he cant hear anyone around him, but, he is real mean to fans though. Some people (phil mickelson, fred couples, etc.) they are nice people, with a good game, good job, and love the fans! I really never see Tiger shake someones hand while going to the next hole...No!... He doesnt really sign autographs... Phil mickelson is a crowd-pleaser. He says hi to everyone, hi-5's everyone, thats why people like to be with phil on a golf course, and not Tiger.
