1. Dave presented a check for $200 for cashing to the plaintiff Bob, who owned a check cashing company. After Bob gave Dave the cash, and deducted a nominal fee, a thief stole the money from Daves hands. Dave immediately notified Tom, his employer who issued him the check. Tom then issued another check and stopped payment on the check held by Bob. Bob brought suit against Tom for the full face amount of the check. Who wins?
