Test water 1st..
"Accidentally" brush by her ass when she walks pass you and apologise.
While she's talking to you, compliment her hair smells really nice and go near to her ear take a deep breath as if smelling and let out some air into her ear.
Read her palm fortune and stroke her palm nicely with compliments to her skin.
Take peeks at her as she did to you and make sure she knows you're looking.
