Imagine the following scenario. A teacher in a German Musikhochschule is offered a paid week in a sunny resort. All she has to do is listen to hopefuls for a few hours a day and pick a winner from a list of students of the professor who invited her. If she plays ball, the chairman might let one of her pupils take the fourth prize. The rewards would swiftly follow. As a teacher of an international prize-winner, our anonymous friend might then be able to double her private fees and promise all future students that they will have prizes.
