I just don't go to the Cinema any more.
Fully grown Adults grazing on fast-food, the distracting glow from mobile phones, the constant, "Why did they do that?", "Who's he?", from confused Girlfriends.
I can wait until the Bluray is £10 and watch it on my TV (which doesn't seem any worse quality than the cinema).
The only time I approve of eating during a film is at Raleighwood (Raleigh, North Carolina) where the cinema is also a Diner. I watched "Pulp Fiction" there 3 times. It was a perfect way to watch Travolta and Thurman, in Jack Rabbit Slims, whilst being served a tasty Burger in Raleighwood. 100% Americana experience.
