Almost everything I hear from clients I consider to be wrong. And I politely explain to them why that is, I get into their assumptions and reasons for thinking what they do, and try to convince them of why it is not the case. I never mock, I never suggest that they are idiots, and were I to start shirking if they disagreed with me, I wouldn't then make them pay while I continued to shirk.
