Rob did two great things: 1) He did not trust the source, and questioned the authenticity. 2) He actually called him out on BS when he continued The first false message from Joe is interesting, but once Rob replies, and Joe continues trying to push the lie, that's a little dick'ish. The second Rob replied, with his first, and extremely professional response, I would have apologized/congratulated him, and explained what I was doing. Continuing the charade invites deserved anger. I don't like being lied to either, especially when I know the person was lying and keeps pushing the lie.
