It's been a long time since I posted here, but wanted to add a comment.
Firstly, I have no time for people who behave like this. Losing your temper on a golf course is not acceptable, let alone throwing clubs.
However, I would like to draw everyone's attention to the fact that in his youth, Bobby Jones was known for throwing clubs, and during a tournament he hit a lady spectator with a club that he threw.
The national media ridiculed him, other golfers publicly denounced him, but he was given a second chance, and not only did he never throw a club again, but he went on to become one of golf's most respected gentlemen.
The point is, until he was called out on it, he didn't change. In fact, those who didn't punish him for his earlier (non-injury-causing) club throwing are complicit in the eventual injury caused. But also, that the first time he was reprimanded he was given a second chance.
It's one thing to kick a guy out if he's already been warned. But if many people know that a guy has behaved like this, and no one has picked him up on it, morally (though maybe not legally) it's probably correct to give a second chance with a very stern warning plus financial compensation.
That's just my two pence worth... and I should add that a) again, this guy still sounds like a nasty piece of work, b) I didn't read the final two pages and so am not commenting here on any unacceptable behaviour of the guy post-the event, and c) that Bobby did own up to what he'd done, so if this guy didn't then maybe that changes things...
