It's more the glaring holes in his story that is creating this reaction. He's said the club have been back in touch with him, but makes no mention of what they said.
From personal experience, we had a table last season at a corporate function in the RDU, guy at our table won the raffle for the match ball. When his ticket was pulled out, he went up, got a picture taken with a player, then the ball was placed in a carrier bag and handed to him.
Before this guy had his picture taken with the ball, it must have existed at that point and he's failed to explain how the ball came to be removed from his possession.
