Yes, when I was in Japan.
I was in preschool and I had these mean lady for a teacher. She use to give all the bad kids a spanking.
We were on some fieldtrip at a museum and I began to walk ahead of the group. She yanked me back and gave me a spanking.
I never said anything to my parents about it because I thought they'd be mad at me for walking ahead of the group. I finally mentioned something to them about it when I was 10. They were PISSED when I told them that my teacher had done this. My parents' approach is that they can hit me if they want but nobody else is allowed to lay a finger on me.
Oh well, it was too late then to do anything about it. It didn't scar me for life or anything.
