I doubt most people with "N95" masks have real N95 masks. Most I see are the folding cone types that don't looks like they seal well to the face and are unverified and manufactured in China to no real standards. I have a box of 3M verified N95 masks for woodworking and they are bad enough wearing for a few minutes while sanding; I don't think anyone would wear them all day no matter what the perceived risk was.
