In the eyes of the law there is not a "semi public" space. A retail establishment, theater, or out on the street in all public, and generally people can take all the pictures and video recordings they want without permission.
YouTube is fun to watch with instances like this. I watched one where a guy and some woman got into a car accident. The woman was acting weird so the guy was videoing it. She kept hollering at him to stop it and even the cop that showed up told her he could record if he wanted to. Eventually the woman attacked the guy recording, got cuffed and charged with assault.
I agree, the guy was kinda creepy, but them if the OP was clocked as a crossdresser the guy taking the picture might feel the OP was creepy! It's going to happen. You dress and don't blend, some people are going to get weird about it.
