A building contractor was being paid by the week for a job
that was likely to stretch over 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.
“I know,” the owner said. “But last week I overpaid you two
hundred dollars, and you never complained.”
The contractor said. “Well, I don’t mind an occasional mis-
take. But when it gets to be a habit, I feel I have to call
it to your attention.”
