I fell asleep that night to Jennifer muttering to herself about how the electric garbage disposal worked if there was no electricity in the house. Her incessant mumblings were starting to make me cranky.
The garbage disposal worked not because it was powered by electricity but because it was powered by magic. It really was that simple. She needed to pay a pound of flesh for the mansion, and she had. Now, nothing anyone did would make that garbage disposal work again.
In contrast, the price that Fleur had to pay was simply choking on her food every few bites. But unlike Jennifer, she didn't bitch and complain about it; she just continued eating. It wasn't like she had asked for a crap ton of food, either. Just enough to take the edge of hunger off.
She wasn't Greedy, so her price wasn't steep.
