New Rule? Old Rule?

I'm pretty sure it's not a new rule, I just put that in the title, cuz it sounds interesting.

At a tournament last weekend
Team B loses the serve as the ball gets shanked toward the back wall.
Team B player rounds up ball and tosses it to Team A -- over the net.

Team A players kept insisting they should get a penalty point for that. Has anyone ever heard of such a thing?
