Aaaah, adrenaline fueled conflicts, aren't they great?
I personally think that at the begining of each day, a hard boiled egg should be shot from about 20-30 feet away. I saw a picture of that once, I think from pbreview, and it scared the bejeebus out of me. For some reason, people dont seem to grasp the danger involved. My boss even tells them that the paintball will go through their eyes and into the backs of their skulls (which I take to be bollocks but its still a grisly mental image).
As for controlling punters, it really depends on the situation. If there's paint flying thick and fast, you've got to be physical and get him on the ground asap. I can appreciate the need for professionalism but trying to reason with a punter when every second could bring on disaster just isn't going to work.
