The nature of his advice isn't the problem (although it is pretty bad advice if I say so myself) but the fact that he pulled it out of his ass without any logical thinking toward the situation. In my opinion, he tried to look like a badass but when it backfired he played it off as if he was legitimately trying to give a helpful solution. Then when it backfired even more he tried victimizing himself.
That's just my take on things. Hopefully he'll come in, apologize, pull his stuff together, and we'll be on our way but I highly doubt that will happen.
