Interesting concept, but I am afraid this will (if ever) only work in the US.

Here in the UK and in Europe people would get the cheap tickets and then still smuggle their own drinks and snacks into the movies, because that's what we've always done and that's the culture here - especially among the millenials who think they can outsmart everything and everyone and feel entitled so. Also people on this side of the pond don't really fancy the massive buckets of sugary drinks or XXL sized hot dogs like our American friends.
