Good one ^^ Definitely a good opener to go with at a bar!
Next time I'd follow with what Dan said, go with a bit of light teasing. "Pffft that's a girls drink!" If she pulls out that she is in fact a girl then say "Well that gives you a good idea of what half of the guys in here are like doesn't it" *point out in a random direction to a guy with a similar drink*
Only one tip I can offer with nightclub game, can't quote the source as I honestly can't remember but never go 'bobbing', if she can't hear you then don't suddenly lean into her to talk into her ear. Make sure your the rock who's standing still and she's the one leaning into you to hear what your saying or talking into your ear.
Just do this by tilting your head slightly so your ear is facing her and beckoning with a 'come hither' motion with your finger. Works wonders
