Things Get Ugly Between Two Legends At Charity Event -Agassi-Sampras-

The backstory: In his excellent autobiography "Open," Andre Agassi describes Pete Sampras as a tightwad and tells about a time he saw Pete tip a valet a mere 2 bucks once. He claimed that was all the money he had.

Agassi, a generous man, who has given a small fortune to numerous charities including his own foundation for underprivileged children in Las Vegas, describes himself as being aghast at Pete's chintziness.

Now watch as the tension rises between the two to the considerable discomfort of Roger Federer and Rafael Nadal who were playing doubles with them at a freaking charity event.
