Dissuasion in public is a real art for women. They don't want you to talk to them but they also don't want to be mean and rude to you unless they have to do so. Presumably, they are busy and don't need a bunch of idiots fawning all over them, but they would prefer not hearing "bitch" or "cunt" from every man that walked by them. So, who is best at it?
I've found Russian women, or at least women I think are Russian, can convey just the right expression of, "Thank you for smiling at me and acknowledging my beauty and that you want to fuck me right now, you horny old devil, but I've got a better offer out there somewhere, so I will pass."
