Yes, sometimes they do. It depends on setting, your "presence/attitude", etc. Seems to happen at the worst of times.
Rewind to a few years ago...waiting for my D, trying to play it straight til it's over so I can keep my kid and my stuff, and I'm in a pawn shop checking out a guitar. I drew the attention of a lovely little brunette with a gorgeous backside, I wasn't trying at all, the last thing on my mind.
She said hi to me first, she broke away from her convo with her friend...I was stunned. I wasn't at my game, I don't think it was the guitar.
I think it was because I was doing something I really liked, and showed interest in it.
Women seem to like this about a man. Doesn't matter if you're a salesman in a gun shop or a fine chef.
Knowing a lot about one thing seems to trigger women in an interesting way. If we could just control/predict when it might happen...
I sometimes wish I could have asked her out and gotten away with something, she was really my type.
