Cone Cups?

I don't understand cone-shaped cups in offices. They have to be the most impractical invention. They don't sit on your desk, and they are hard to hold and drink. AND, they aren't that much cheaper than small, paper cups. It's like those collapsible camping cups that liquids squeeze out of the holes on, or a bowl that can't hold liquids. I just don't get them. Who invents this crap?
