She caught him.Took off her belt and gave him a much needed spanking I think.The kid's Dad seen it all and called the Cops.
Now.You are not supposed to lay a hand on someone's else kid for starts.Maybe the line was crossed there.I bet this little angel has never been corrected by his parents a day in his life.
But I do admire the clerk for taking matters into her own hands.
I would have been more pleased if she had took that belt to the kid's uncaring so called Dad.
