I firmly believe that what goes around comes around.
This woman will get her just desserts and what will happen to her will be a lot worse than what she did to you.
I had a manager borrow a lot of money from me (sob story) and I couldn't get her to pay me back even though we worked in the same place. She eventually had me transferred to avoid facing me.
I wanted to blow the whistle so bad but had given her my word not to say anything.
I never did.
But in the end she ended up losing her job because she was borrowing from everyone! Now, she's working at McDonalds!
