I don't like the whole popcorn thing. It started during the Great Depression simply because both movies and popcorn were very cheap, a $10 sack of corn could serve many, many portions, so it was some affordable luxury for cash-strapped people. Fast forward to today, every movie selling huge buckets of popcorn, not cheap anymore despite the production costs are still very low, and thus attracting the kind of clientele (fats) who think it is entirely normal to chew 2+ hours.
