> Popcorn, it seems, was the original clandestine movie snack. Haha. I have a big coat with inner bags where I can fit two 1.5 lt sodas, I always sneak snacks when going with my friends, since, at least in my country, every snack is ridiculously overpriced (around 5 to 10 times the original price).
It may be a bit of a faux pas, but I've often openly gone into cinemas with my own food/drink and no one seems to mind. (Side-note: I highly recommend edamame-in-the-pod for a cinema snack. Quiet, healthy, cheap, comes with its own hydration and lasts a long time.)
