I can't remember if I've seen this!
I've definitely seen the trailer before, and because it's one of those trailers that gives away a lot about the story, I feel like I know the story but I can't remember whether I've seen the whole movie.
Here's a thing that could help: that old guy she is chatting to from time to time at the diner where she works - does he by any chance end up giving her a lot of money (either by dying and making her his heir or otherwise?) I seem to have this vague recollection, so if it's accurate it means I must have seen it.
