A tender made as a basis for acquiring a concurrent right to an exchange due from the party to whom tender is made may be made conditional on the performance by the latter of his obligation;89 but a tender of performance of an absolute obligation of the debtor must be unconditional, since the debt itself is unconditional. Therefore, a condition that a payment shall be taken in full discharge or as a compromise of the debtor's obligation,90 or that the creditor shall give a receipt in full of all demands,91 or even a receipt for the money tendered,92 invalidates a tender. Objection by the creditor on this ground, however, must be made at the time in order to be effective.93 Moreover a debtor may, when making an absolute tender, protest that the amount claimed by the creditor and tendered by himself is excessive and thereby reserve a right to sue to recover a portion of what he tenders.94
