My grandmother kept getting calls from sears for replacement windows, finally one day my grandfather was in the house so he told them to go ahead and come out and quote them. They didn't realize they lived about 1.5 hours from the closest sears so they drove all the way out, spent a couple hours measuring their old farm house, gave him the quote and he handed it back and told them it was too expensive so they drive the 1.5 hours back. Pretty much wasted their whole day so they never called again.
