Throughout the whole film they talked and giggled, they continuously plied themselves with wine and the one next to me was even texting, the light from his phone particularly annoying me. They also took it in turns to get up and go for a pee during the showing which must have annoyed the people behind them as well.
I would have complained, but to talk to the theatre staff I would have had to make lots of people move to let me out and I thought this would be rude, and as there were seven of the drunks, all of whom were younger and bigger than me I thought it best not to tackle them myself. I did smile however when the drunk next to me dropped his phone and had to wait until the cinema emptied at the end of the film before he could retrieve it.
What most surprised me however was the foul smell of the wine. I used to love wine of course and would happily drink gallons, but the stench wafting across made me fell quite sick, and that is a measure of how far I have come since my own drunken days.
It's a shame drunks are allowed in somewhere like the BFI where film is supposed to be taken seriously. I would love to have had a Marlon Brando style character to have a sly word with, and perhaps have the offenders quietly removed...
