Worse is when folk try and take the sweets out quietly. It's not gonna happen, just take them out man and get 'em in yer gob!
I rarely go to the cinema but have found one that's not all that popular with the masses so it's generally ok. I went to the one in Cramlington a while back and there were loads of people eating sandwiches and drinking pop. Hahahaha! I haven't been back there since.
I once accompanied the bloke who used to do a lot of film reviews for, I think, Sky. I ended up sitting along from a family who had taken take-away Indian cuisine in with them … I couldn't believe it! That was yonks ago. That was a special screening of whatever the film was - I've long-since forgotten.
Before I went in to watch BBTL I went to the market to get some cheaper, chocolate-type sweets. Those and my little bottle of rosé went down very quietly.
