I think it could also be a potential for distraction that prevents you from even starting to begin with a productivity task. If you were in an open plan coffee shop things would be different as you don't expect someone to tap you on the shoulder with some arbitrary "urgent" bug to fix or fix the printer because you're "the I.T. guy". So you actually begin real work rather than only do tiny chunks of busy work.
