My mate (guy who taught me bouncer ropes lol) did jsut that tho, and nearly went to court.... bunch of guys were refusing to leave a place (this is when I worked the bar not the door) and when the girl I was on bar with went over to collect their drinks one spat at her

Well Danny, bouncer, just jumped straight in (he was dating said bird) and grabbed one by the wrist. Unfortunately the guy he grabbed took a swing with the other arm.... Big mistake
Danny snapped his wrist round the wrong way (broke it) then hed butted the guy and bust his nose

then whacked another guy who was trying to get in on it in the ribs and cracked two of em (ribs I mean)
Oops
They left, but pressed charges

Fortunately didn't end up in court tho....
