Yes to the first, an no to the latter. (Of course you could use the ladder to look over into the stall...)

I'm with the "privacy" people--I've actually had the door the one of the changing rooms at the downtown Minneapolis Target swiing open after I was sure I'd locked it.

What gets me are how many bathroom stalls (at least in the men's rooms) don't have coat hooks. I mean, I got this big, honking duster, and I don't want to put it on the floor. I have enough trouble with things falling out of my coat pockets as it is. In fact, I'm pretty sure that's how I lost two flash drives when I was in Winnipeg...
