10 Worst Ways To Behave At Concerts: How You're Ruining It For Everyone →
From the entire list I agree only with #8 – I hate it when people are choosing to stand in the middle of the crowd and hold damn flags or banners. On a Morrissey concert one time I had a serious argument with one guy, he was from Spain I think, he wouldn’t put down his damn flag so I had to talk some sense into him.
On another note, I think they missed one thing on this list – smokers. I absolutely hate it when people get drunk (or worse yet when they are sober) and wave around and stage dive with their damn cigarettes.
