Ah, Just what we need.

More disruption to watching the game, whilst a muppet with a red hot tip attempts to squeeze past the numptie coming the other way who is trying to balance 4 pints at once.

Have these people never heard of Betting shops or Pubs?

Closing them at kick off would solve this?

They already close at KO, I had to trail to Totesport in Holbeck to collect my winnings.

Did they let you do it?
Yeah i know but the OP said about in-game betting.

keep all betting 'pods' open 1/2 hour after the hooter for winnings?

Nah, you'd still get them trying to put bets on at the last minute before returning to their seats 5 mins after the game has started.

Who could resist the 50 to 1 odds of Scotty being MOM?
