When they try this and get it so wrong it is teeth-gnashing material. Hmph. No emoticon for that.
It is even more infuriating when they mishear what I say and go off on a tangent that is completely unfounded, and contradict me when I say they are wrong.
However, I have had two occasions where it did help, because the way the T phrased it made me understand something I hadn't.
Does that balance the other times? Maybe.
