This is usually what happens, though in my case my boss (Lead Dev) is already telling them what isn't possible and what doesn't make sense. Some clients just insist for months until we finally give them what they want and they see we're not talking out of our rears. But yeah I understand all that, it's just silly to me to waste time and money doing things that will not be useful for the end-product. I guess I'll be numb to the silliness eventually...
