For me, it was usually something like: "Hi (insert SP's name here)... I'm AJ, its so nice to finally meet you!" I always try to use the lady's name. Its more personal.
Depending on the situation, this is usually greeted with a warm embrace and sometimes a kiss, which usually morphs into some LFK, DFK. We then make some small talk, and I usually compliment her on her outfit, her shoes, or her general appearance, and then excuse myself to freshen up.
With one exception, I have always established a rapport with the ladies I see, though e-mail and/ or text, so that awkward first moment never happens. Its one of the reasons I prefer to see indies.
