I remember trips to the local flea pit when I was a child. First with my mum, I remember seeing Chitty Chitty Bang Bang, Bedknobs and Broomsticks and Herbie.
Later, in the six weeks holiday, a group of us (primary school age) were allowed to go alone with a couple of parents picking us up when it had finished.
The thing I remember is we used to dance in the aisle when the local ads came on (usually for some local Indian restaurant). This was frowned on by the staff! Happy Days.
I think these days (not been for years) people try and sneak their own food in - as you say,
@jennifer1967 ,the popcorn is a rip off.
