i have zero issue with anyone who is actually sitting there, at the stadium, and is only getting up to eat, defecate, and i'll even make an allowance through show day for an hour to go shower - not for their own hygiene, but rather so i don't have to smell them. come show day, though - no shower breaks allowed. suck it up buttercup.
it's not my cup of tea; i'd never waste that much time just so bono can snot on me - but hey, to each their own.
it's the douchebags who hold spots and put their name on a list and disappear for hours upon hours at a time, take naps back at the hotel, and whatnot that piss me off. if you want the spot, you show up and you wait. period. coming to a show from out of town or out of country doesn't make you any more important than the fan who lives there and either doesn't have the financial means to travel the world following the band, and/or has a family and/or job that prevents them from doing so. it. just. doesn't.
i remember sitting at the bar before the now infamous @U2 party and laughing at all the people with numbers in the low double digits, even single digits, flooding past me. who, exactly, was on line?
