Just doing lines off the top of the seat in front to keep entertained pre match then :whistle: :moo:
Sorry for the cliche, but I bet you're fun at parties.
That isn't the issue the OP is trying to solve. It makes perfect sense to allow people to take drinks from the concourse to the open air seating in the current climate and, yes, I'd rather have a bit of beer on my clothes than either catch Covid or to be pulled up for not socially distancing...
Yes there's a specific rule for professional league football that covers drinking in sight of the pitch (which is why concourses have upstairs access to the seats and lounges have curtains).
There's no sense in the alcohol ban with sight of the game laws anyway. In almost any other sport you can have a pint in your seat during the game and in many other countries whilst watching football.
Someone still thinks it's 1985
