This sounds like a tough one, but, personally i wouldent use a direct opener for day game, i would ask where to find a store in the knowlege that its in the same dierection they are walking, they say, 'yeh its that way' you say 'well could you take me there'(perhaps something a little more subtle would be better, im just generalising) and then they should say 'sure' (if not then its not worth your trouble), you strike up a conversation about whatever is on your mind and play your mid-game well, make them know your not a creep, and i can assure you at least a #-close.

Now my ultimate weakness is day-game, so take my advice with a pinch of salt, and always remember that old cliche ,'if at first you dont succed, try and try again', a rejection isnt the end of the world man.
