And so why is it a "bad idea" to insist a customer sign off on his own follies that he insists on having implemented?
All you keep saying is that one shouldn't take those jobs. No shit, Sherlock. Wow, brainiac thinking there. I'm just f****ng stunned by the brilliance of that idea. I have to sit down for a moment here. Wait, I am sitting... I think I'll go lay down and just let that sink in for a decade or so.
Now.
Assuming everyone and their dog has already thought of that and recognizing that sometimes those of us out in the real world who actually do installs themselves are sometimes faced with the need to take on such customers, or worse, have existing customers come up with this kind of idiocy in the middle of a project... do explain how it's a bad idea to insist that the fool sign off on his own follies that he insists on having implemented?
