Stephen Potter on Caddies

“His plan was simple. If he found, at the club-house, that his opponent was rather humbly dressed, he would wear the smart outfit. If the conditions were reversed, out would come the frayed pin-stripe trousers, the stringy clubs and the fair-isle sweater. ‘And I don’t want a caddie,’ he would say. Of course, in his correct clothes, he would automatically order a caddie, calling for ‘Bob’, and mumbling something about ‘Must have Bob. He knows my game. Caddied for me in the Northern Amateur.’”
