Just about everyone who works on Wall Street has heard the stories about Jamie Dimon. The one about his shutting down the gyms and pulling the fresh flowers at J.P. Morgan Chase. (That story is true.) And the one about his grilling limo drivers parked in front of headquarters to find out who’d ordered the Lincolns, then screaming at the culprits for wasting money. (That one’s apocryphal, but Dimon doesn’t mind people repeating it, because fear helps him control costs.)
