Greg, I don't follow your post; from R96's description, the saleswoman was either deliberately lying or had no knowledge of what she was claiming. In either case, that couldn't be fairly described as "honesty".
No, in the second case, it could be fairly described as honesty. She could be honest but wrong. If someone agrees with you, it can be because he honestly shares your opinion, or because he is dishonest, but thinks agreeing with you is the best way to get from you what he wants. I think one should prize disagreement.
