Apart from a brief return of the cash turnstiles in the regional footy days I can't remember the last time you didn't have to queue twice to get in?
After I stopped buying the season tickets I would go to the ground during the week to buy tickets to save buying them on the day, now I go on line, pick the best seats together I can find (often at least four, sometimes six+) and pay with my card. It usually takes 5mins top.
The online ticket system works brilliantly for me.
