Reference he Mickleson v Woods article.
(scroll down to read what Tiger Woods' caddie Steve Williams had to say about Phil Mickelson).

I have obviously not had as much interaction with the two players concerned as Mr Williams, but I can only relate my experiences of the two players attitude, particularly to golf fans, which I encountered during the 2004 Open Championship at Troon.
Whilst Mr Woods appeared aloof and seemed to actively avoid signing autographs and interacting with spectators, Mr Mickleson was entirely the opposite.
After round 3, Phil Mickelson spent a good 45 minutes or so at the walkway from the 18th green, signing autographs and chatting to many spectators who were gathered there.
Despite a number of promptings by his entourage, who were trying to get him to the press tent for his appointment with the media, Mr. Mickleson continued signing and chatting until he really had no option but to go to the press tent.
His whole demeanour and attitude towards the paying public on that occasion was a very positive one and attracted many favourable comments from the spectators he had taken the time to speak with.
Having only seen him on TV prior to that occasion, where I have to say he did not come across well, I can honestly say that he rose greatly in my estimation after my experience of him in 2004.
On the other hand, Mr Woods, who always comes across on the media as friendly and approachable, was, in reality, entirely the opposite.
From my experience of the two, I know which one I would rather be partnered with if I was looking for an enjoyable round of golf with a multiple major winner.
