Sixteen-year-old student Darryl Chong wanted to impress his new girlfriend Siew Leng. One evening, he took her by taxi to a fancy restaurant for dinner; the bill came up to $200. After dinner, he sent her home in another taxi. After bidding her goodnight, Darryl remembered that he had been warned by his school discipline master about his messy hair. He needed to get a haircut before going to school the next day, and proceeded to the neighbourhood barber to get a haircut. While at the barbers, he saw a notice on the wall that the barber was looking for a part-time worker to clean up the barbershop each evening for two hours at $10 per hour. Hoping to make some extra money after school, Darryl applied for the job and got the job. Using your understanding of contracts by minors, explain if each of the contacts are binding on Darryl.
