If we want to allow for cash refunds of patron credit, instead of sending a zero amount for patron_credit, we could always ensure we send the full payment amount. The key is to inform the server in some accurate way of the actual credit being "used", as we do not receive this from the patron, but rather retrieve it from their account.
