Only 1 in five years. 5th game of match - VC got a little upset that HC was, OMG,
cheering that her team lost a point. (actually he was cheering that one of his kids that had just hammered a kill - giving them the serve, and never even looked at her team) VC was demanding that partner give him a card for UC. He didn't see any UC until in her tantrum she kicked over a chair. AND followed that by tossing a duffle bag onto the playing surface. Bye Bye!
