I went to see a Lostprophets concert in the seating area of the Manchester Evening News Arena. Almost everyone was standing, however, the seats there are set up quite steeply so it is not the end of the world if someone would prefer to sit.

The way I see it, if the person behind you wants to sit, it is courtesy for you to sit, after all you've bought tickets for the seating area, and some people may be unable to stand for a length of time.

What annoys me though is that at concerts it is not strictly enforced, however down at Elland Road the Leeds United stewards are that paranoid you can't stand up for more than two minutes without being told to sit. I have my other grievances in that department too
