Such a requirement would be subject to too many variables, including the possibility that creditors or their counsel could hold a payment check without depositing it, that banks and check cashing agencies have holding policies of their own, and other potential factors that would unfairly lengthen the duration of the debtor's obligation to pay post judgment interest. We are not persuaded to hold otherwise by Doodan v. Szawlinsky, 179 A.2d 661 (Pa.Super. 1962), cited by the Perels. There, the judgment debtor — an insurer — tried to pay just half of a $10,000 judgment by issuing a check of $5,348.35 to the plaintiff.
