Yahoo's CEO criticized for oversleeping and missing business dinner

Yahoo's CEO is making headlines for over-sleeping and missing a business dinner.

Marissa Mayer was nearly two hours late to this year's Cannes Lions, the world's biggest advertising industry event held in France, where she was supposed to discuss Yahoo's new and improved strategy.

She reportedly missed a marketing opportunity with some of the executives who left before she arrived.

"If it were an investor meeting, a board meeting, or a potential acquisition, I am sure she or someone from her team would have woken her up," one top executive told The Wall Street Journal. "It is another instance where she demonstrated that she doesn't understand the value of clients, ad revenue, or agencies."

There are reports that Mayer even had the guests rearrange their schedules so the dinner could be held at 8:30 that night.

Yahoo wouldn't comment on the incident, only saying they value their partnership with all their advertisers.
