> How do you know he's thinking that? The way he was talking, I read him as "well it's obvious that nobody has stopped this behavior so it's fair to assume that not enough people noticed". Wouldn't you agree with that?

I wouldn't. Anyone... everyone... who's worked retail _knows_ this. Anyone who's worked retail management knows this because when you ask to hire people you're told to hire part timers. Two part timers is always better than a full timer, you're told. This is NOT invisible to anyone. It's simply unspoken.
