During a dialogue, trying to run the sentences of another person through some kind of mental compiler and tell them about every error/illogical statement they have made. Seriously, dont start doing that. I makes you look like a smartass. My experience is, a lot of business people say stupid things with a purpose just to move on, even if it is totally illogical, but it is their initiative that helps them to get out of an otherwise difficult situation.
