Ron invites Mark over to his workshop because he needs a license in order to continue selling products. Ron describes how he shouldn’t have to follow government regulations about toxic chemicals because he’s the only one breathing the fumes. If he isn’t bothering others then he doesn’t feel the need to be regulated.
Tom needs to move, but doesn’t have a truck. He enlists the help of Mark because he has a pickup truck and Andy/April because he needs labor. All agree to help even though Tom offers no compensation. Social norms often mean that friends help each other despite not being compensated.
