Consistency....

A builder was being paid weekly for a project would last for several months. He approached the owner of the property and held up the check he'd been given. "This is two hundred dollars less than we agreed on," he said. "That's right," the owner said, "And last week I overpaid you two hundred dollars... Funny, but you never complained." The contractor said, "Well, I don't mind an occasional mistake. But when it gets to be a habit, I feel I have to call it to your attention."
