Carl went to the local bar after work and spent the rest of the evening drinking. When he started to go home, he discovered that his truck had a flat tire, and he began kicking the truck's fenders. When Fred saw the problem and heard Carl ranting in anger at his truck, he offered to give Carl a ten-dollar bill and a ride home for the truck. Carl took the money and sat in the cab of the pickup until Fred could change the tire and drive him home. When Carl couldn't find his truck the next day, he reported his truck stolen. Who owns the truck and why?
