Maurice contracted with Suzanne to feed and walk her Corgi mix dog, Baby, for $100 while Suzanne was on vacation for one week. One day before Suzanne was to leave, Maurice came over and said that Baby would be a significant amount of trouble and that he would have to receive $150 in order to walk and feed Baby. Suzanne reluctantly agreed. When she returned from vacation, she handed Maurice $100 and refused to pay more. Maurice threatens to take her to small claims court. What would be the likely result?
