Firstly, most professional golfers have enough money to keep them happy for the rest of their lives.
Secondly, due to them all being sponsored by golf equipment companies they don't even have to pay for their equipment. They just let them know that they need and hey presto a new one appears.
So as Mark said, fining them is a complete waste of time.
The only way things will get better is for each professional who commits an infringement to miss the next tournament, harsh maybe, especially if you are a spectator and was looking forward to watching a certain player.
I can understand the point about starting with a number of shots added to your score but to be honest, I cannot see the golf authorities, or even the players standing for this.
It is wrong for the professionals to swear or abuse equipment after hitting a bad shot.
