It really comes down to people who hate Serena just got another reason to hate Serena. If someone like Wozniacki or hell even Stosur did this, people would look at the penalty and what it was given for and think ... wow, that is a stupid. Instead, it's wow there goes that angry bitch acting a fool. I think technically the chair ump made the call by the book, but it's a ridiculous rule regarding "outbursts" during points. Technically, a player could make the case that any of the chicks who grunt during their matches are "impeding" their ability to complete a point. I think the chair ump has the ability to exercise leniency in these cases and probably should have done so. Saw something similar with Murray vs. Nadal where Murray changed wrist bands and exceeded the 20 second limit between points. Chair ump did not warn him or anything, understood the situation and let it go.
