I usually get compliments when I am getting a hug. That way the usually shorter girl is near my chest or neck, thus getting a good chance to smell me. The odds of getting a compliment is small because people just don't feel the need to be outwardly polite anymore.
I have heard that people know when I get to a certain location, even if they can't see me, because they smell me. It is no that I smell the same all the time because I don't. I almost always wear something different. They just know it's me. They don't feel like they have to tell me about how I smell, wether good or bad.
That is my experience. I wear for me anyway so I'm not too bothered by it.
