" When Mr. Aching had worked for the old Baron, they had, as men of the world, reached a sensible arrangement, which was that Mr. Aching would do whatever the Baron asked him to do. Provided the Baron asked Mr. Aching to do what Mr. Aching wanted to do and it needed to be done. "

― Terry Pratchett , I Shall Wear Midnight (Discworld, #38; Tiffany Aching, #4)
