(b) Ricky visited a car dealership and test-drove a sedan car. After discussion the price with the salesman, Eric, and learning that he could purchase the car for RM50,000 less than the sticker price, Ricky asked Eric to hold the car for him until 8.00 PM that evening so that he could bring his wife back to see the car. Eric agreed, writing out a note promising not to sell the car before 8.00 PM. The note was written on dealership stationary, but Eric did not sign his name. The dealership broke its promise and sold the car to Jones before 8.00 PM.
