Do you think that this was rude...or was she just trying to be helpful?

I went to the Dr's office today--turns out that I have bronchitis.While the nurse was checking my vital signs,she mentioned that she used to be my size,and is selling her clothes that are now too big for her on e-bay,and that I should check them out.I was appalled ,but did not show it,and graciously thanked her.
