Hey I agree wit all the guys that say buying drinks for women is bull if they try that I say YOU should buy me a drink, kinda shift the power balance away from them. Another thing I would say is that try opening a set by yourself you see a bunch of girls at a table mayby in a bar (clubs pretty noisy) and open wit something like hey me my friend there are having an argument he thinks lady gagga is hotter than rihana i told him he's crazy wat fo you think ? its calm not threatning she dont know wat intentions you have its a question she may turn to her friends and argue between them you are then accepted into the little group in which all her friends accept you and can chat to i tried that approach at a group of people on a work night out i got so into the group that the boss was buying me drinks lol ,but i did make myself sound interesting ( i was a biochemist working for the army ) and they loved it i was getting attention from all the female's the guys other than the boss did not like me i could have included them but they didnt seem into me but it takes practice i didnt get any numbers or that my goal was to open and i did so i was happy
