Savaretti offered to pay his niece, Wilma, $2,000 if she would agree to give up eating meat and pastries and drinking caffeinated beverages for six months. Wilma agreed and gave up these activities for six months. At the end of those six months, Savaretti refused to give Wilma the $2,000, arguing that because giving up caffeine, meat, and pastries was beneficial to her health, she suffered no detriment and was owed nothing. Wilma took Savaretti to small claims court and demanded payment of the $2,000. She argued that because she had the legal right to consume the caffeine, meat, and pastries, she suffered a legal detriment and was entitled to her money. How should the referee rule in this case
