Clean Desk Dirty Floor

Is there a reason for wanting a desk without a lick of paper, a pen, or a paperclip on top, but meanwhile having MOUNDS of papers around the perimeter of the room. Do these people feel 'neat' because the plane on which they are working looks efficient, but God help them if they try to leave the room. Virtual obstical course I tell ya. Maybe this is why these sorts often hibernate in their offices all day, only to emerge to take their pee at 10 and 2 and microwave their lunch at 12:55 (yup, Plannerism too!)
