A Fortune 500 CEO once said that when he had to choose between two candidates with similar qualifications, he gave the position to the candidate with the better handshake.

Is his reaction extreme? Perhaps, but on the other hand, consider the following study by Dr. Allen Konopacki for the Incomm Center in Chicago: A quarter was left in the coin return of a public telephone. If a stranger took the coin after using the phone, one of the research students would walk up and ask whether the person had seen the quarter.
