Because I like to leave a bit of a gap in front of me so I'm not heavy breathing onto the back of the person in front of me, I always seem to signpost myself as the pathway towards the front. Doesn't seem to matter how far front or back I am, I always seem to get a river of people walking past me mid gig.
Also irritated by the people who arrive 2 minutes before the start of the headliner, squeeze through the crowd and then stand in my comfort gap. No mate, I just stepped aside so you could get past, I didn't invite you to join us, keep moving!
Yes - hate the talkers!
