Brogue Notice if you are under 15 you have to be with an adult in c1871. Hopefully means it becomes a bit more behaved over there now
You would hope it would have some impact, but most of the people who seem to be 'giving it large' are between 16 and 21 - who've drunk about three or four pints before the game and drink more at half-time. If the club wanted to limit the anti-social behaviour that occurs in Club 1871, they'd stop alcohol sales in that stand (and remove access to the units behind the East Stand that sell alcohol).
I've noticed at away games, the handful of times the home club hasn't had alcohol sales in the ground there's been much less anti-social behaviour during the game from our fans. I'm fairly certain it would have a major impact, not least as a sizable number of people wouldn't sit in Club 1871 because of it and would be further away from the away supporters as a result (and wouldn't be within distance to engage in that behaviour).
