Try walking around a grocery store with your phone and take a picture of every person you pass. See how they react.

That's the expectation people have for privacy.

Reminds me of the "Surveillance Camera Man" project[1] from a while back, where a guy went around silently filming people in public. People didn't like it and some responded aggressively, even though those same people probably thought nothing of the numerous actual surveillance cameras pointing at them all the time.

There's a whole category of video content called "First Amendment Audits" where people film with big cameras in public and farm people random, and often quite hostile, reactions.
