Really? How many hands have these people got? and good luck having them not knocked over. You could restrict sales to one per person 15 mins before kick off/ second half and have the bars shut during the game. I am not in favour of unrestricted boozing during the game, but I do not see why...
Absolutely in favour, providing the bar is shut whilst the match is in play. Nothing wrong with a pre/post or halftime beer being taken to your seat. A big no to bars being open during the game. No one interested in the game wants that.
