Sometimes the receiver inverts the position, insisting how little the benefit has turned out to him, while the doer insists on its great magnitude to him, eg if at considerable risk one has benefited another to the extent of a drachma, the one insists on the greatness of the risk, the other on the smallness of the money, just as in the repayment of money for there the dispute is on this point the one claims the value of it when it was lent, the other concedes only the value of it now when it is returned, unless they have made an explicit provision in the contract.
