I get where you're coming from, but, there's a difference between not wanting to do a particular thing that your client wants you to do, and doing something different from what a client wants you to do. A better analogy would be going to a prostitute and insisting on a condom, but then the prostitute pokes some holes in it and becomes pregnant "because you seemed lonely so I thought a child might be best for you". That would be a case of requesting one service (protected sex not resulting in pregnancy) but getting an undesirable one (unprotected sex resulting in pregnancy) solely because the service professional disagreed with "what's in the best interest of the client in the view of the [prostitute]". Which, to put it mildly, is not what you paid for. :-) If a hired professional disagrees with a course of action that a customer has explicitly requested, the appropriate action is to decline to enter into a professional services arrangement, or break an existing one. Not just go ahead with whatever you wanted to do anyway because you think its better.
