Reminds me of the apocryphal/anecdotal tale of the management conultant who wanted to fire a "secretary" who he could only find taking coffee breaks and long lunches with lots of different people, only to be told (or finding out after the firing) that the person in question was critical to inter-team dynamics and functioning.
