To be honest, I thought the same thing whilst entering the turnstile for the Charlton match. I handed over my voucher with the correct numerical value on it and was instructed to wait for a moment. The voucher was passed over to a little bald headed fellow wearing half cut glasses and a 1940's suit (the theme music of the Great Escape then played in the background), he asked me to pass him a paper clip that was on the floor, I couldn't see one so he picked it up and started to produce an exact copy of the handed in ticket. Within moments, a perfect copy had been produced, a candle was lit and some melted wax was dripped onto the magnificent piece of artwork and the Wings seal pressed into it creating the wording "admit one".
