I go to a few metal gigs, and there are two distinct areas, the "standing/sitting" area, and the "circle/snake/mosh/whatever pit". If you're in the former, then you should stand/sit and not be a tool. If you're in the latter, then you should go as crazy as you feel like, because that's what the pit is for.
I makes me angry when people stand right on the very edge of the pit and lose their temper at people bumping into them. What do you expect, it's a pit.![]()
