My nickel (we don't have pennies anymore up here hahaha)
Kids see and imitate and emulate - what everyone does they notice -positive and negative
I see it at times as looking for attention
You guys correct - Parents have to set the parameters and boundaries
As for Rory's club toss - tennis has a penalty point for "Abuse of Racquet" -maybe golf should look at that kind of idea
Add a Stroke penalty (DQ might be too harsh methinks) and you'll see less of that for sure
