Daniel, a recent college graduate, is on his way home for the Christmas holidays from his new job. He gets caught in a snowstorm and is taken in by an elderly couple, who provide him with food and shelter. After the snowplows have cleared the roads, Daniel proceeds home. Daniel’s father, Fred, is most appreciative of the elderly couple’s action and promises and in a letter promises to pay them $500. The elderly couple, in desperate need of money, calls Fred and thanks him for the kind offer and says they would gladly accept Fred’s offer. Then, because of a dispute between Daniel and his father, Fred refuses to pay the elderly couple the $500. Discuss whether the couple can hold Fred in contract for the services rendered to Daniel. Awnser should be about a paragraph long.
