Congrats!
I worked in a theatre for a while when I was a teen. It was very easy work...of course, back then we only had 2 screens in the theatre I worked at. The largest in town only had 4! LOL! Since all the theatres were the same company we could go anywhere in town for free...usually myself plus one, although on slow nights they'd let me bring 3 or 4 friends for free.
I think my job consisted of selling tix mostly, then kicking back, eating popcorn and chit-chatting for an hour or 2 until the next round. Oh, and playing frogger and centipede! I'm sure things are different with these multiplexes!
