Serena Williams, notice the double standards with which she's judged for getting angry on court compared to someone like McEnroe, who is everyone's favourite commentator.
For all his tantrums on court John McEnroe didn't say this to a lineswoman;
"I swear to God I'll f.....g take the ball and shove it down your f.....g throat." - Serena Williams did.
"Afterwards, she was unrepentant: "An apology from me? How many people yell at linespeople? I see it happening all the time. I don't know how many times I have seen that happen. I am a professional. I'm not the beggar, like, 'Please, please, please, let me have another chance,' because it was the rules and I play by the rules."
