Something I have noticed, in college is that, in places outside of parties/bars, the sooner I indicate in some way, via a joke or flirting, that I find a girl attractive/hot, I get a much higher success rate of going out with her.

So my question to you is, for men or women, how long should a man wait before making it clear in some way he is attracted to a woman he meets?

Conditions:

  1. The location is not a nightclub or bar.

  2. The man is not cat-calling, he has to at least start a normal conversation about something.

Thoughts?
