An interior decorator asked a woodworker she met at a crafts fair to build a curly maple armoire. they entered into a written contract, with a contract price of $6,500 to be paid upon the decorator's receipt of the armoire. when the work was completed, the woodworker shipped the armoire to the decorator. after inspecting it, the decorator felt that it was not of the same high level of workmanship as she was expecting, given the other furniture that the woodworker had showcased at the fair, and a good faith dispute arose between the parties as to the workmanship. the decorator sent the woodworker a check for $4,000 marked "payment in full." the woodworker indorsed and cashed the check, then sued the decorator to recover the $2,500 balance. what would most courts likely hold?
