Problem
Ben is 15 years old. He went to a bookshop to buy a Dunhill pen for the price of RM20,000. He didn't have sufficient cash with him. The owner of the bookshop, Mamat, recognised Ben as the son of Datuk Rich, the billionaire, and agreed to accept an IOU from Ben. Ben has now refused to honour his IOU.
Can Mamat enforce the IOU against Datuk Rich?
