A mandatum is the name given to any bailment where the bailee gratuitously does some work on the bailed article. Reimbursement for actual necessary and useful expenses incurred in preserving the property-bailed or in fulfilling the objects of the bailment, may be recovered even in the case of a mandatum.9 Unauthorized expenditure is not the subject of a reimbursement.10
