I got chucked out of a cinema for doing my own food.
My argument was that the prices they charged were ridiculous, and I hadn't had a good barbecue in ages.
My 'Cinema coat' has a poachers pocket, it holds 4 big bags of Maltesers, two XL popcorn, 1 lg Merry Maid caramels, 4 tubs of ice-cream and a 2ltr bottle of Coke (diet)
