Three money orders were stolen from representatives of American Express. Prior to being stolen, the money orders bore the pre-printed signature of the Chairman of American Express but were blank as to payee, date, sender, and amount. The stolen money orders were then presented for payment at Chuckie Enterprise, Inc. (Chuckie's), a check cashing firm, with all the necessary information filled in. After confirming the appropriate indorsement and checking photo identifications, Chuckie's paid the face amounts to the bearers minus a two percent fee. The money orders eventually reached American Express, which after having noted on its "fraud log" that the money orders were stolen, refused the pay the amounts of the money orders. Robert Triffin, a commercial discounter, purchased the dishonored money orders from Chuckie's and received assignment from Chuckie's of all rights, claims, and interests. Triffin then sued American Express demanding payment of the stolen money orders. The court found the money orders constituted negotiable instruments. Does American Express have to pay Triffin
