I have never ever in my life experienced this happening. Not seen it happen even once in all my time and travel in many countries. Actually never known it to happen even when I lived in the US.You are very lucky to have never seen children throw ugly tantrums in public. When it happens, you are just so grateful for the peace and quiet when the parent removes the child from the scene, and it feels satisfying on an instinctive level when the parent delivers a few smacks as well. Sometimes the punishment doesn't work to restore peace, but it does more often than not.Spoiled children who throw public tantrums do exist, and yes, the blame for that lies on the parents for not teaching the child to be respectful and responsible members of family and society from a young age. Spanking is effective at a very young age before the child can use reason, but after that spanking is less effective and can be counter productive.
