Sam Student borrowed $1K from his cousin. Sam and the cousin became involved in a heated disagreement when the cousin began to press Sam for repayment of the loan. Finally, Sam wrote a check for $190 to the cousin and conspicuously wrote on the check in big letters that it was full and final payment for the $1K loan. In need of money, the cousin cashed the check and demanded the remaining $810 from Sam. Sam refused to pay, claiming that they had entered into an accord and satisfaction that discharged Sam's obligation to pay anything more.
