He's so melted down that he can't see that he's the cause of his own problem. Of course he can't swing a club now, not after that. Imagine being in the group with him. At the moment the video ended, if I was in his group I would have told him to go back in or go home because he just ruined our games too. I fired a golf buddy once because he had a mini meltdown and wouldn't stop, while I was having the hottest 5 hole start of my life. It takes a lot to make me mad on the course but that would do it.
I bet after he saw the video, he was embarrassed. At least I hope so. Also, if you yell like that at someone, you can't get all indignant if they threaten you with violence. He's lucky he didn't get decked, IMO.
People, fuck 'em.
