Like Xfman said, go early. most the bars/clubs where I go, play music way too loud, one of the gambits I run early in the night goes like this.
CHASE: Do you come here often?
HB: No.
Chase: Well let me give you a little tour. (kino to get her attention focused), well that over there thats the front door, you probably came in that way, and I can see that you found the bar already, and that over there, thats the dance floor, I gotta run but if your lucky I can properly introduce you later.
If she interrupts your verbal tour neg her, something like, "oh sweetheart pardon me for talking while you interrupt", or the classic neg to her friend "is she always this rude" but the key is let her interrupt but steal conversational dominance back with the neg. This whole routine is run cocky funny. Later when the music is too loud, i pawn a set near the target. If you worked it right in the beginning she will approach and isolate you to the dance floor. Dance, but make her work for you. then take her to a more quiet place in the bar and run your normal game & close.
the best part is that you cut out on your terms and if it worked she approaches you at that point you wont need to do much talking. i do this several times a night, especially if im feeling lazy or just out with the boys.
