I agree with you Richard, as a painting contractor for very many years, people are always looking to get more and more out of you. I had to give an estimate to a lady a few weeks ago who had more stuff around her home than a thrift store including heavy furniture, stuff all over the floor and junk everywhere. I knew if I accepted the job id be a furniture mover and cleaner. I also agree this article makes it seem like the contractor is out to rip off the customers. Fact is I always leave doing more work than agreed upon. It doesn't bother me since the customer is always satisfied. Just saying
Oh, where to begin? Let me start with 'watered down paint'. 25-50% before the material gets to the site? Impossible. You would basically be painting with water at that point. It would be less of a hassle, and cost, to simply use proper material. You would be forced to apply three coats instead of two, as the coverage would be horrible. Whatever cost you think might be saved in materials would be lost in labor.
