Agree with all of this, and l'm sorry to say that it's the sort of thing one expects to encounter watching the national team, or the really big Premier League games.
But at non-league, grassroots level? . . . no way.
The day that there needs to be security guards stationed at the food kiosks, is the day that l give up watching football at the Amex, and retreat to the non-league game at l'il old Horsham YMCA every week.
Not too many shenanigans at the Gorings Mead tea bar.
