does she like me or is she just being friendly? please help?

Ok so a couple months back I moved to a new city for school and there's a subway (restaurant) that I've started going to pretty regularly. There's a girl who works there and granted for just about everybody she asks them how they are doing. But its just the exchange of good how are you? good. But with me we usually have an actual conversation like on Monday she was telling me that she got to hold some of her friends exotic reptiles. And I then told her I have a pet snapping turtle which she thought was really cool. And then she started telling me about this reptile show she and her friend were going to this weekend. She tells me these kinda things a lot. I guess I wanna know is she is just being friendly for her job or is there anything more?
