When Angela and Wendy arrived at Sai Kung Pier, they asked a coxswain, called Keung, whether he could provide motorboat rental and driving the boat for wakeboarding for the day. Keung quoted $1500 cash payment for his wage for driving the motorboat and the motorboat rental charge for the day. Wendy then asked Keung if there were wakeboards for them to use. Keung replied Wendy that there were wakeboards on his motorboat. Afterward, Angela and Wendy paid $1500 to Keung and Keung drove the motorboat with Angela and Wendy to open sea area for wakeboarding.
