I went to high school with the ticket taker
I haven't seen her since high school, but I know the ticket taker (Vondria Bergen - she was Vondria Andrews before she got married). I've not seen the movie (yet) - after ten years(!), but it's on cable later this morning so I'm going to have to watch to catch her.
She was one of the best artists I've ever met - in all ways. If you name an artistic medium or method, she was naturally accomplished at a phenom level.
She was also one of the best people at school. I think if anyone had a problem and needed someone to talk to - beyond their normal circle of friends - after all, there are some things people won't discuss with their friends, they felt they could trust Vondria.
