A suggestion for the Holte Pub - why not have a simple website that allows people to reserve their entry for an upcoming game. It could go "live" say a week before a fixture for people with tickets to register. Those who don't have Internet access could text a number.
People would give their seat number or booking reference.
By only allowing people to express their interest in turning up say a week before the match, it allows:
a) eager season ticket holders to gain access (a whole week before a game, fewer tickets would have been sold)
people who are very eager to go have the opportunity to confirm they're going up to a week in advance (possibly increasing likelihood of turning up)
Now out of 40,000 people many will obviously be disappointed, but at least this way it rewards those who buy tickets early and show an interest in going to the pub.
