When you're at the movies, do you :

Depends whether I enjoyed the film. I sometimes make a dirty protest about Hollywood's asinine offerings.

I absolutely hate movie theaters.
I am paying $8 for a ticket to sit in a dark, cold room full of strangers to watch something that I could just as easily watch while in the comfort of my own home while eating food that doesn't cost me about as much as half a tank of gas would for my car and is probably cleaner and healthier too. And, I don't have to worry about the screaming baby and the Mother that doesn't notice it until after the best scene is over with, the teenagers throwing popcorn and trying to be "gangsta" whatever that means, OR Peewee Herman. Fuck movie theaters.

But when I do go (which was usually for dates, telling a guy all of this will scare him off quick), I clean up my garbage. I'm a grown-up. Grown-ups can clean up after themselves.

It depends. If I have a candy bar or something I usually leave it on the floor. Anything bigger or messier than that, I put in the trash can.

I leave all the garbage there.

When i was younger, i jobbed as a cleaner/ticket controller in a cinema.
Call it spite in that i had to do this for other people and now want it done for me, call me lazy that despite knowing about it i don't act different, or just take my word for it that in MOST cinemas, you don't want to look under your seat.(because often, there is too little time before the next movie start to PROPERLY clean, so stuff is just thrown there and left to the proper house-cleaning-contractors the next morning.)

i cant remember tbh

I HATE the movie theater!! Won't catch me there. But based on my actions in other settings, I'd definitely clean up after myself.
