Only the best of the best make it to the Upper Floor. They have to be the very best servant girls ever. Because there is no way I’m going to allow anything less in the dining hall when I have my friends over.
Even if they do no nothing but quietly sit on their knees and not move and not say a word…. It’s still worth having. It just adds to the ambience.
And it reminds everyone in the room who their master is at the end of the day!
