Let her think what she wants to. I would let the manager know about what he/she said. The manager would probably thank you, because that could end up being a customer service problem. Just think if she told that to someone who was not financially sound...that could lose business for the company...not only to that particular customer, but also everyone else they tell. That could be a small problem that escalates into a large one. In the retail business...no matter what it is you are selling, you have one chance to impress the customer. I would say that employee didn't get the job done. I would tell the manager that the staff may need some updating on the various morphs that are out there. I remember somewhere seeing a rare morph for 20,000. Show that one to the sales employee...
Sorry for the long response, but that's just my opinion lol...
