Drive-ins were a big thing in the Midwest where I grew up and they were of course really cheap, it was the fun thing to do when you didn't have a lot of money to pile up the kids in the station wagon and head to the drive-in.
They're starting to pop up around the country now and I checked the prices for the ones closest to us and one is around 50 quid for a family of four. 50 quid! And I found it weird they charged per person (the 50 quid is for two adults and two kids). The other one near us is rightly charging per car but that's still £38.
I would have liked to have taken the kids so they can experience it but that just seems really expensive for a film they've already seen 100 times (Toy Story, Jungle Book etc).
AIBU? I know they have overheads, etc and people will probably pay it just to get out and have something to do but yikes.
