i rarely go to the cinema anymore, but when i do i usually prefer Dos Equis, i mean buy popcorn and a soda. blame nostalgia, but i actually like theater popcorn with genuine artificial imitation butter flavor on it, and i haven't met a vendor yet who wouldn't give me my soda sans ice if asked, so i at least get a decent amount for my tree-fiddy.
that said, sometimes i really want something that they just don't sell in theaters -not pizza or anything like that, i'm still talking snack food. usually it's jelly beans; i love coconut-flavored jelly beans, and the only place to get them is the candy shop in the mall across from the theater. the way i see it, if they don't sell what i want then i'm not diminishing their profits by bringing it in, especially since i'll probably still get popcorn and soda anyway.
