On the 11th floor of Procter & Gamble’s Cincinnati office, AG Lafley has just rolled up the sleeves of his open-necked blue shirt and is standing at the windows of his “huddle room”, hoisting up the metal blinds to let the sunshine in before he settles down for lunch.

The food, covered by the kind of metal lids I last remember seeing in my school canteen, is laid out on the table in his modest meeting room. There is no linen, fancy silverware or waiting staff. There is no bottle of wine resting on the table or even water in a jug.
