Sure, but it was just an example. What about if I was with my lover, and I didn't want my wife to know? If someone from the staff knew my wife, how do I know they won't send the video to her?

What if I was drunk and tripped or made a fool of myself in some other way and I didn't want that to end up on YouTube or /r/PublicFreakout on Reddit?

Etc., etc.

We just don't know. Of course I could sue the person if what's been done is illegal, but it's a video and the damage would be done and hard to repair.

Well that person who knows your wife probably only needs their voice to tell your wife...

From what I’ve seen, there may be a display in view of the staff and/or public. But the DVR and controls are usually locked up for the simple reason the owner doesn’t want to have to pay to call in a tech every time an employee monkeys with the system.
