Ever witness a memorable spanking in public?

What happened?

The second paragraph of the following old post by me describes my over-hearing a terrible beating of a friend by his father. Though I did not see it, the experience profoundly affected me. It had never occurred to me a parent would ever punish a child so severely It was horrible!

Wow that's awful. I've personally never had the experience of witnessing an event that didn't leave me shaken up/upset. But I know some other readers have, how amazing would it be to walk up on a consensual adult spanking?
