I certainly agree with the sentiments of being honest up-front, of working best when not bothered, and of the importance IT plays in business. I don't agree with the attitude you are proposing though. What benefit is it to drive your client crazy by working slowly? And why be so inflexible when discussing future work? There are much more tactful ways of explaining realistic timelines and procedures to clients without doing the equivalent of saying "talk to the hand 'cos the face ain't listening". IT already has a bad reputation from people that act like self-important jerks. Lets not advocate more of it.

Good communication and management of clients is a core part of consulting. Refusing to discuss things through with your client is not "doing it the right way".
