I was thinking that the golf club was overkill but then I guess no one knows what was said. Also, sometimes when people see the red mist they just want to destroy their opponent.

People in these sort of jobs probably have to put up with an unbelievable amount of shit from the public on a daily basis. Surprised something like this hasn't been reported as to happening sooner.

EDIT: If you look at the gif, it looks like a guy and a girl that are both getting a golf club whupping!
