Blackboards: Not only a great Iranian film from 2001 but seemingly the only way a pub can spread its message to its punters. But what I fail to understand is where pubs went wrong and misunderstood the whole point of blackboards. You write on them with chalk. For ease of erasability. There are actually people whose job it is to go round painting pictures of grapes, bottles of wine and jolly butchers on these things. And we can’t rub these poorly painted abominations off.
