William billed Denise $200 for cleaning her computer of viruses, but Denise complained: "My computer is still behaving weirdly." It turned out that William had missed some viruses in hidden files. Denise said, "I'm paying you only $100 by check marked 'Paid in Full.'" William cashed the check and then sent Denise a statement showing $100 still owing. Denise owes the other $100.
