Yahoo CEO Marissa Mayer isn’t the only one catching 40 winks, reports MarketWatch.

Yahoo Inc. Chief Executive Marissa Mayer was late for a meeting with clients at the Cannes advertising festival after she reportedly fell asleep. Last Tuesday, Interpublic Group put together a fancy dinner at L’Oasis for Mayer to mingle with marketers such as Mondelez International MDLZ, but Mayer showed up two hours late and, according to reports, told people a nap had gone awry.
