At my local non league club, Dulwich Hamlet, you can drink where ever you want for League games, as the rules are made by the Isthmian rather than the FA/ Football league.
However on Saturday, because it was an FA Vase game, and therefore under FA rules, we were told by the stewards we couldn't take booze out of the bar as they had to follow FA rules. Yet, you could stay in the bar, with it's huge window that runs the length of the pitch and watch from there with your pint.
This confused me, because I always thought the FA rule was 'No drink in sight of the pitch', hence the sheet at Franchise?
Dulwich Hamlet....now there's a good name, back to the 50's and early 60's when the Amateur Cup Final was a big thing with massive crowds at Wembley. From the start in English football, there had been a schism between Professionalism and Amateurism
