also another technique is to hand out a card and just be honest...."Hi my name is _____, im attracted to u and would like to get to know you. U dont have to give me a yes or no, but here is a card just and u can decide on your own time"
boom!, it may be dull and not on some super mack shyt, but u took your shoot, it might hit the target
I think people only do that so they won't hear the rejection or the sound of her dumping the card somewhere when you walk away.
