The nurse opened her mouth to speak, but Tiffany didn't allow the words any space. 'The cook has told me that you are a very religious woman, always on your knees, and that is fine by me, absolutely fine, but didn't it ever occur to you to take a mop and bucket down there with you? People don't need prayers, Miss Spruce; they need you to do the job in front of you, Miss Spruce. And I have had enough of you, Miss Spruce, and especially of your lovely white coat. I think Roland was very impressed by your wonderful white coat, but I am not, Miss Spruce, because you never do anything that will get it dirty.'
- Terry Pratchett, I Shall Wear Midnight
