In tennis circles, Jelena Jankovic is known for her constant talking and complaining throughout matches. During the quarterfinals against Serena Williams at the Dubai Duty Free Championships last Thursday, Jankovic had an exchange with the chair umpire and got upset at what she perceived as Williams stalling on match point. 

It got to the point where announcer David Mercer had had enough of Jelena's complaints exclaiming, "Oh, do shut up, Jelena! It drives me insane!" He went even further, "We don't need this." Apparently Mercer had a dinner reservation he wanted to keep.

The crowd mic also picked up a fan saying, "We've got your back, Serena!"

After Williams closed out the match, she and Jankovic had a discussion at the net, but it was more to calm Jelena down. 

Remember when David Mercer is calling your match, don't complain too much otherwise you'll incur his wrath.
