Every time I caught a bit of tennis today there was ructions going on.
First Fognini.
Then Djok swearing at the umpire over the amount of time Bautista-Agut was taking between points.
DelPotro had a run-in with the umpire over a call and wasn't happy and the next time the umpire got down to check and it went DelPotro's way he spread his arms out towards him for a hug, which of course he didn't get 
At the end of Deliciano's doubles match there was another disagreement whether the ball was in or out and Fele took out his phone and took a photo of the mark!
