I really don't understand why people think they should be able to eat and drink at the cinema - can't they go two hours without? That and the constant chatter and use of mobile phones is the reason I stopped going to the cinema in 1998.
When I take my grandchildren I take sweets and bottles in my bag. The staff are just teenagers who aren't paid enough to ask to search anyone's bag.
When I was a kid my mum used to take a picnic - sandwiches, fruit, sweets and drinks. In those days you were there for hours - main film, B film, cartoons and Pathe news reels. You needed a meal with that lot!
I'm just happy with a bottle of drink. I do find the noise of rustling bags, crunching and munching on popcorn etc., a bit annoying. The last time I went to a cinema there was hardly anyone in there and it was a peak time viewing of the The Last Jedi.
The old cinema location in my town used to have several newsagents near it and they'd sell all the same stuff at about a 3rd of the price. We used to get all our drinks popcorn etc there.
