How to guys feel about being recorded?

I was sitting in a local cafe doing homework on my laptop when a person I've seen around but don't know too well walks towards while recording me with his Iphone. He asked some stupid questions while recording me and then walked away. I got upset about that. I kinda like to have my privacy… So I told the Cafe' manager about it and left. How do you guys feels about this situation?

Its illegal w/ out permission

I think being recorded is fine as I carry little shame.
