It seems like te stupidest thing to me. Why are you going to attack someone who has politely asked you and/or your child to behave themselves or at least stop actively doing something harmful
Why the hell would they disincentivize their kids when someone has just given them an out to have a teachable moment and possibly nudge their kid behave better and possibly for the parent?
Some people respond to correction by lashing out. That’s true for literally everything. Telling them you can’t smoke there, not washing their hands is gross, you need to take off your shoes in my house, etc.
“Get your car out of the bike lane” gets 'em real mad every time.
Also, ‘wear a mask’
