Jon Ronson, a Boing Boing pal and author of many great books, including So You've Been Publicly Shamed, Frank, The Psychopath Test, Lost At Sea, Men Who Stare At Goats, and Them, was greeted by this "lovely, then ominous" note from hotel housekeeping. I'm sure Jon is already a good tipper, and this note only served to remind him of that fact.
