General. The holes in the ceiling are unacceptable . However to think that there wouldn't be broken bottles, glasses etc in a pub where EVERY person is there to watch the football, and everyone a Villa fan at that is just a pipe dream on derby day . The derby brings passion and stupidness in equal measure . People you see at games who normally wouldn't say boo to a goose go crazy .When you have a city rivalry that literally splits it and friends straight down the middle this is the result. I can't think that I would EVER throw beer or coke in a friends house but The Holte is a pub . A beautifully restored pub but still a pub at the end of the day. With the way our culture is and has been for hundreds of years a pub is a place to go to drink alcohol and let your let your hair down. Broken glass and damage is unfortunately a side effect of that letting off of steam.
As has been echoed before , maybe making the Holte guests only when the derby comes around is the best way to go.
