By direct I mean something along the lines of "Hey I thought you were cute, I was wondering if I could get your phone number?" Getting to the point asap to not waste the other persons time.

vs trying to hold a conversation with someone.

I guess this is more in the context of day game. I think night game is different as you are both in a fixed location most of the time. But in day game someone might be busy and on the go.

What do you guys think on which route is best?
