Is the Client always right?

So I just booked a commercial shoot for an up and coming high end custom home builder in Springfield, Mo. Before I book any shoot, I always speak with the client to make sure that we both have a crystal clear understanding of the expectations. In this initial chat I was asking him what it is that he wanted and how he wanted these lifestyle & environmental type shots to look and what the message was that he was trying to convey.  It became very apparent to me very quickly that what he wanted just simply wouldn't work and most importantly, the images would probably be crap...  I had a very real moral dilemma there as I wanted to do the shoot as it would pay well however,  I knew that the client would not get the results that he was hoping for.  I decided that honesty was and is the best policy. Does anyone hire a plumber and tell the plumber how to do his job?  No, we hire a professional to do a job because he / she is theoretically an expert in their field. So I was honest with the potential client and in a very nice and professional manner told him that his ideas wouldn't work and why. I then gave him a couple of suggestions and then held my breath...  I did get the gig and he did thank me for not just pointing out the obvious (to me), but giving him solid recommendations as well. The client is calling us because he or she wants a "PRO", we need to remember that!!!
