World famous tennis champion Serena Williams was in San Francisco this week, and on Tuesday she decided to grab some dinner at Mission Chinese Food and catch up with an old friend. At some point in the evening, an unfortunate thing happened to her that so many of us have likewise suffered: Her phone was stolen. However, instead of letting it go, the twenty-one Grand Slam title holder leapt out of her chair and chased down the thief.

Williams set the scene with a post on her Facebook page, describing the incident.

"[So] this guy is standing next to me and something (I have now dubbed it my SUPERHERO sense) told me to watch him," explained Williams. "My phone was sitting in the chair but I just didn't feel right. He was there too long."

The plot thickened.

"'Is he a customer?' I thought 'Is he waiting on the bathroom?' nonetheless I tried to shake this eerie feeling," she recalled. "Than when least expected low and behold this common petty thief grabbed my phone and swiftly left."

Williams promptly gave chase.

"Not thinking I reacted (hence the superwoman photo) I jumped up, weaved my way in and out of the cozy restaurant (leaping over a chair or two) and chased him down," she wrote. "He began to run but I was too fast. (Those sprints came in handy) I was upon him in a flash!"

She got confronted the thief, who apparently stammered something about accidentally taking the wrong phone, and managed to get her phone back from the man.

In the end, Williams notes that you should always stand up for yourself and the things you believe in.

Always listen to your superhero inner voice. Always keep your things close! Fight for what's right. Stand for what you believe in! Be a superhero! When I got back into the restaurant I received a standing ovation. I was proud. I just showed every man in there I can stand up to bully's and other men. It was a win for the ladies!

Just because you are a lady don't be afraid to step up to any challenge and not be a victim but a hero!
