Rome is a huge city and as with any huge city, it has a traffic problem. Stan Wawrinka experienced some of that when he arrived in Rome and his transport got delayed.
He didn't have any problem complaining about it on social media calling the transportation service the worst on the ATP Tour.
"Is @InteBNLdItalia the worst @atptour transportation service ?"
Fans were quick to crticize him for that blatant call out in the comments.
