Are you new? [Perspective change]

You look at the girl behind the counter as if you were thinking. "I'm pretty often here, so I would remember a pretty face like yours, if you were here before. When did you start?" The new girl is quite pretty and the clothes suit her really well. "Today." "Did you work behind a counter before?" "No." "Any other jobs like this?" "No." "Where's Susan today? Isn't this normally her day?" "Sick." You raise your eyebrows. "Not very talkative, are we?" "No." "Can you at least tell me your name?" "No."

You start to get the suspicion, that this is just an act. It's not the first time you've seen this, several girls before her played hard to get before they unbent and started flirting with you. Granted, none of them ever actually hooked up with you, but judging by how defensive this one is, she might have a lot of tension built up in her. You wonder what the best way is to approach this situation.
