Two things stick out in my mind:
1. The bus company also carries mail bags from town-to-town. The driver pulls up in the main square in front of the post office, loads/unloads mail bags, sweeps out his bus, and moves on.
2. There was a sign on the castle gates telling people that the castle was actually in use, as the Prince's home, and as such, you couldn't come in without a personal invitation. On the other hand, about once per year, the Prince invites the entire country over for a glass of wine.
