I threw some of that karma back today - I wrote a note and sent it off the Banana Republic. I mentioned how much I enjoyed shopping at their stores, and mentioned by name the manager at that store location, saying that she in particular made the past weekend's shopping experience much more pleasant - and that I found her sales approach exceptional and very professional. Did not go into details about exactly why - don't need to get her into hot water for letting me walk out the door with expensive merchandise!
