VIDEO: "I don't want to be here" - a tired and cranky Serena Williams smacks down reporter
In fairness, there's nothing worse than being asked why aren't you smiling.
And Serena Williams certainly didn't appreciate - not after she had just beating her sister as well.
The American stormed into the US Open semi final with victory over Venus and she is just two victories away from completing the calendar grand slam having accrued success in Australia, France and Wimbledon already this year.
But she was being annoyed by reporters after her quarter final win, especially by one of them who wasn't fully satisfied with her demeanour.
She quickly put him in his place though with a, "you're not making it super enjoyable."
Imagine he had asked Roy Keane the same thing.
