Sidney entered into a contract for $35,000 with MacDonald Roofing Co., Inc., to reroof his building. Sidney made his initial payment by writing a check for $17,500 payable to “MacDonald Roofing Company, Inc., and Friendly Supply Company.” MacDonald took the check to Friendly and requested an indorsement, which Friendly provided. When MacDonald failed to complete the roofing work, Sidney filed suit for damages against Friendly. Sidney argued that Friendly was liable as an indorser. Do you agree?
