Was debating whether to post on here as the festival, for a first timer, was absolutely brilliant and I would love to do it annually but this post struck a chord with my only "panic" moment of the weekend as the chairs debacle wasn't just during Elton.
We managed to get down the front for Sophie Ellis-Bextor and stayed through the end of Cat Stevens. We left immediately after his set and couldn't find a way out of the front pit, left or right. Ironically, there was (comparatively) lots of room right at the front but the further back you went there were people in camping chairs for the last 25% or so of the front pit refusing to move for anybody. To the extent that I actually lost my balance in the crush of people that was building up behind me, also trying to leave the pit. Tried to reason with a few of them, saying we were trying to get out, not trying to nick their spot etc and they steadfastly refused to move- even got called an ar*ehole as we were attempting to leave!
As a tall guy, 6'6, I managed to shout across to the security guys in between the crush barriers and he said if we were leaving just to come up and he would lift us over. Amazingly, even after hearing this entire conversation, one person whose camping chair was set up right at the back barrier refused to get up to let us over the fence until the security guard told her where to go.
So, yeah, I would absolutely ban camping chairs from the front pit. less of an issue with people sitting down on the ground- they were all fine as they would shuffle out the way to let people past but the chairs were downright dangerous despite the relative serenity right at the front and in the centre.
Final gripe, which is more bemusing than anything, was the sheer volume of litter strewn around the fields (particularly the Pyramid) which was just incredibly lazy. 99% of people had a backpack. Just put your empty tins in there are find a bin when you leave!
