Is it a compliment when a lot of men just stare but never approach?

Like a compliment that they think she is attractive.

There was even a deliverer who I accidentally had eye contact with because I was playing a game and he stared as if he was surprised or something. I can never really tell what kind of stare but most men just stare surprised or look me up and down and sometimes smile or still be surprised.
