Rentokil's chief executive is a rationalist, a man with a logical answer to everything, who regards commerce as an intellectual exercise.
Businessmen, like politicians or generals, are frequently divided into two sorts: visionaries and logicians. The visionaries are leaders, men driven by grand plans, exhorting and cajoling their employees and customers, creating market through strength of will. Often they are unpleasant, cruel and tyrannical. But, usually through their ability to shape events to their desire, they have a certain stature. They inspire awe, if not admiration.
