I too, have witnessed a youngster crying like a baby when eliminated. To be fair, he was in the A division which he had no business being in and got his clock cleaned.
I've also seen the adults throwing temper tantrums when a switch doesn't score or a tight sling shot propels a ball into an outlane. That's actually pretty cool to see.
These incidents took place almost a thousand miles apart.
I'd love to have a player whine that I was watching him without me being entered in the tourney. People like that can go [edited by poster before a moderator ejects me].
