• He noticed that one of the servants at his 11,000 square foot Palm Beach mansion wore squeaky rubber soled shoes;
• He ate $400 worth of stone crabs there during his 15 minute lunches; and
• He neglected to invite his rival -- KKR partner, Henry Kravis-- to his lavish 60th birthday celebration -- to which a huge portrait of Schwarzman, which usually hangs in his living room, was shipped -- because he had never been invited to Kravis's home.
