An agitated Ray Dalio once ordered an extensive study of urine on the men's room floor at Bridgewater, new book says

• Ray Dalio once ordered a probe into urine on the men's room floor, a new book says.
• Dalio reportedly asked staff to take notes on who entered the bathroom and how clean they left it.
• Bridgewater said Dalio did complain about restroom tidiness, but the book passage is "exaggerated" and "false."

Billionaire hedge fund manager Ray Dalio, known for his exhaustive list of employee standards called The Principles, once ordered an investigation into who had left urine on the men's room floor, according to a new book out Tuesday from New York Times finance reporter Rob Copeland.
