OUTSIDE VIEW

Here's an innocent photo of a smiling woman entering what appears to be a boxed-like mirrored structure (which, btw, can be found on a sidewalk in downtown Houston). Can you guess what she's stepping into?
INSIDE VIEW

Guess no further! It's a public toilet with 2-way mirrors on the inside. You can't see in, but you can see out! Could you "conduct your business", if you could see people walk closely past you? Or worse, have them stop and look at themselves while you're still whistlin' Dixie? I shudder at the thought. LoL.
