Serena was among the American athletes who came to France to watch Team USA superstars’ medal-winning in the Paris Olympics during the week.

But her experience as a tourist was likely less than what she had hoped for. Williams, an Olympic gold medalist herself in 2012, complained about the service at The Peninsula Paris in a post on X.

"Yikes @peninsulaparis I've been denied access to the rooftop to eat in (an) empty restaurant of nicer places," she wrote on the social media platform, "but never with my kids, always a first."

The Peninsula Paris appeared to apologize to Williams in a reply.

"Unfortunately, our rooftop bar was indeed fully booked and the only unoccupied tables you saw belonged to our gourmet restaurant, L’Oiseau Blanc, which was fully reserved.

"We have always been honored to welcome you and will always be to welcome you again."

She didn’t respond to the hotel’s apology. On her Instagram Stories, Williams posted a video of the United States men's volleyball matchup against Brazil.

Williams was among the torch bearers for the Paris Olympics.
