What the hell ever happened to customer satisfaction?
I've hung 150lb flat panel tv's on cantilever mounts anchored into cinder block and done pull ups from it to show the customer the stability. I know what I'm doing, and I've never had a problem. I don't care what DirecTV or the trainers say, if done properly, a mount to a block wall can be incredibly stable. When I did fulfillment, I tried to accomodate the customer. it's their home. As long as I can feasibly accomplish what they want, I'll do it. Unfortunately, strict QC requirements have limited the scope of installs and killed customer satisfaction. It's pitiful.
I'm sorry you couldn't get the dish mounted where you wanted it, but the tech knows that if he does what you want, he may not get paid. I understand why you're upset, but it's not his fault. In today's suit-happy world, customer satisfaction has made way for legal protection.
