Please answer the following question: What is the full name of the person that persuades the salesman to let him test drive a hot rod?  Answer the above question based on the context below:  18 year old Johnnie Simpson lives with his father and Aunt Martha, after his mother died when he was three. His dad is strict with Johnnie and is constantly criticizing him. Johnnie has a girlfriend, Betty Palmer, who works as a waitress at the local drive-in. Maurie Weston, the town bully, owns a fancy hot rod and teases Johnny about him not being allowed to have a car. One night at the drive in, Maurie makes a move on Betty, but she rebuffs his advances, and ends up letting Johnnie drive her home in her brother's car. On the way there, Johnnie gets stopped by the police for speeding and driving recklessly. The police drive him home and give his dad a summons to appear in court with his son. His father berates him for his careless behavior, while Aunt Martha suggests that maybe he should spend more time with his son. Later, Johnnie gets a summer job at a gas station, without telling his dad. The owner of the station is building a hot rod to race and encourages Johnnie to help him with it. After his father finds out about his new job, he demands that he quit and come to work for him in his real estate office. Later that night, Johnnie and Betty are having dinner together when Maurie again tries to make a move on Betty, and Johnnie gets mad and challenges him to a fight. Maurie suggest that they race instead, and although Johnnie doesn't have a car, he agrees to meet him in an hour. Betty refuses to lend him her brother's car again, so Johnnie asks her to take him to a used car lot where he persuades the salesman to let him test drive a hot rod. Johnnie promises to return the car the next morning.
Answer:
Johnnie Simpson
