"It's quite normal, because there's a lot of physical labor in our prison," Peter explained reasonably. "Even if it's not 6 hours, just working for two or three hours can be exhausting. But they're prisoners, after all, so they have to accept the punishment that comes with their crimes!"
Peter's explanation seemed reasonable enough, and any regular tax agency personnel would have been easily fooled by it.

After spending over two hours, although somewhat physically and mentally fatigued, the trip was generally very worthwhile.
