I like eating popcorn in the cinema, but it's not necessary for me.

Oh, why didn't I find this earlier...
is this the place where I can say that I go absolutely mental if someone eats and drinks in cinema? :-) I mean, I understand it's supposed to be that way, them even selling hte stuff, and I really try to endure it if people keep quiet. But if they start making noises with bags or I can hear them bite their popcorn... I usually tell them to keep quiet. They can watch DVDs at home if they don't care about the story of a film. But missing pieces of dialogue because people chat and eat... makes me go up walls :-)
I'm a bit more relaxed if it's childrens films or comedy. And I'm fine with eating before a film starts... or after.
I remember, when I was in Lord of the Rings, waiting a year for that film, someone crushed his popcorn bag exactly in the quiet moment when Aragorn and Arwen whisper to each other in elvish. Good thing they were several rows behind me... :-)
Otherwise I'm a nice person, be assured :-)

I've ususally eaten all my sweets before the film has even started!

Actually I have usually eaten at least 3/4 before the film starts. Then, I do take handfuls. I'm not eating sweeties at the moment so nothing at The Imitation Game.
