"girls go to the nightclubs or bars without money on purpose... cuz they know they won't need it"
I was a lucky guy with 3 women for roomates at 1 time and i can say they used to do this all the time.
SOmetimes if we were out with some guys they would even tell the guys that we were their dates and that as long as they kept sending us drinks, we would leave them alone and they could talk to them
So even a guy can get free drinks from a guy, you just have to be gay or have a women roomate and some very stupid men
