Gig drunks, do they p*ss you off?.?

When I go to gigs ( I go to many) I'll admit I like to have a couple of drinks. But, I am always respect full of those around me. Rowdy gig drunks really annoy me though. They come in from the bar before the headliner comes on then just shove their way to the front sending smaller people flying, a complete disregard for those around them. I like nothing more than jumping around and getting involved at gigs, but people who are off their face to tend to just get in the way...
