Does This Girl Want me to Ask Her Out?

I went into One Hour Photo today and when I walked in this really really really cute half asian half white girl yelled hi and asked me if I am a green lantern fan because my tshirt had green lantern on it. I then told her my problem with my phone and she kept smiling and joking a bit. I was about to go and then she's like wait let me write the prices on of the camera on my card and she did and she sort of bent over and wrote it and I could see her amazing rack. but anyways she like smiled and said my name is Sarah and I gave you my card and she said I didnt catch your name what is it? and I told her and shes like come in to buy your new camera when I am here and I said I'll call her when I am coming in. Should I ask her out when I go in again? I'm not sure if I should but I dont think workers usually ask their customers their names.
