Some volunteers in the London Olympics Opening Ceremonies have called colleagues \"crass\" and \"disrespectful\" for selling props from the show. Items including costumes, a book read to the audience by J.K. Rowling, programs and confetti from the Opening Ceremonies have popped up for sale on eBay and London 2012 officials said they were happy to see the props \"go to a good home,\" The Daily Telegraph reported Monday. However, some of the volunteers said they were disappointed with their colleagues for selling the items. \"I think it is a bit crass really. While we were told they were ours and were not told not to auction them, I still think it is very disrespectful,\" one performer said. \"A group of us joked ... as to how much our costumes would sell on eBay but it was very tongue in cheek. It is not really in the spirit, is it?\" another said.
