R soles and m8 by the sound of it..
Why did you consider them pro's?
A bit of extra loving would've sorted them out surely,as for throwing bottles at them it would make you the culprit and perhaps your in the wrong "sport" if you consider physical assault acceptable,paintball at walk-on level is a release of aggression...on the field.
They were there to have a good time @ everyone elses expense,even the site owners and because in their lack of control they've prolly lost a few
regular players,they should have dealt with it..perhaps the call of the dollar was the overiding factor.
You have to learn how to deal with these tools,anyway name and shame who gives a f**k if they're m8's,as long as you stand by what you say...
