my typical response to the "buy me a drink" thing

if a girl asks me to buy her a drink, i make her qualify herself to me first. i say something like i dont just buy anyone a drink you know, you gotta show me youre worth the effort first.

then let her prove herself with the lying game or something like that. if she passes, fair enough and ill buy her a drink, if not i might let her get me one if she seems fun.

this shows her that im challenging and that im screening for something better than just an attractive dumb fuckbuddy (even if im not really). if she wont play along and show you shes worth your time, then she probably isnt, so ill leave her to buy her own drink and go back to my friends
