I have a bone to pick with the original author of this post.
While I completely agree with the sentiment, about how it is not cool to videotape other people, and embarrass them via the internet, I would like to point out one thing...

I do concur, bosses, managers, owners, et al. should have no business knowing what you do on your free time, but I do take exception to the other half of that statement.
If you put your family, personal relationships, and most importantly children, in serious jeopardy by altering your consciousness at a rock concert, maybe it's time you seriously reconsidered your responsibilities, and straightened out your priorities. But to each is own.
