Roger Federer, winner of 19 Grand Slam titles and arguably the greatest tennis player of all time, is just like you. He makes silly faces (though his come after reaching the quarters of Shanghai with a straight-set win over Alexandr Dolgopolov) and he even takes public transportation.
While acclimatizing to life in Shanghai for the ATP Masters 1000, Federer took a ride on the local metro.
Of course, your trip on the underground would be monotonous and repetitive, while his was a spectacle. Fans and reporters clamored for a moment with the Swiss.
Who knows, maybe next time you're on your commute to work with your eyes down and mind engrossed in a podcast, Federer will be standing right next to you.
