I haven't been to the movies in the States in ages, so I'm not sure if you have this.
In Japan, whenever you order food at the movies it comes on these oblong trays. One side is smaller than the other.
By the way, this large popcorn and two drinks (we bought coffee) were 1000 yen.
Then when you sit in your seat, you put the smaller part of the tray into the cup holder and it holds up the whole tray!
Another thing about movies in Japan is that when you buy your ticket, you reserve your seat.
I like this because you can choose where you want to sit and some theatres have love seat seating so if you go as a couple you can sit together without an arm rest coming between you.
Do your movie theatres have anything interesting?
