Characters: Giles' dad, Giles (if somewhat silently).
"Never bargain like that again, not with me, young man. A motorcycle? A motorcycle in exchange for passing your exams? Your grandmother didn't leave you that money so you could spend it on some deathtrap the first chance you got. Besides, I expect you to always do your very best and not with an expectation of personal reward. What happens in the future, when a poor Slayer, holding the fate of the World in her hands, looks to you for help? Are you going to fold your arms and demand, 'What's in it for me?' It doesn't work that way."
