I found a story on this site some time ago, but I have been unable to find it since.
It is about a young, college educated girl applying for a job at a supermarket, I think it was called Shop and Save or something like that, but is told that she is overqualified. The boss is worried that she will leave as soon as a better job comes up, but she needs the money immediately. So she agrees to sign a contract agreeing to work there for a year.
As soon as she signs, she age progresses into a middle aged, working class woman and her boss tells her that this will make her fit in better with her coworkers.
