This is a hard one to rate. On the one hand, the story is fascinating, but also one I already knew about &so I don‘t feel I learned anything new. I also had a hard time sympathizing w/Rachel. Yes, what happened to her was awful, but she also allowed for Anna to pay for all their other outings. I do agree she shouldn‘t have to pay for Anna‘s or the other guests portions, but I think Rachel should have owed Amer Express her expenses for that trip.
