Well, the most amateur guy on this site, back again. Yeah it's me.
I am kidding.

Actually I need some help from helpful friends in here.
First of all, I am in the USA. (Cal) A few days ago when I was shopping I met one girl. She is salesgirl in sportswear shop. When I saw her, I feel something at the first sight. She is funny, helpful and always smiling person. Yes I know she must be like that in business life but when I see her in the shop, she always speaking with another employees like that. So, I think her behaviours are not drama. (We spoke about music and general issues a little bit and it was really nice talk. She looked like enjoy our talk.)
The main issue is I am new in USA and I wonder that how can I meet her? I mean, how can I learn her phone number or Facebook? She know I am from Europe. I don't know, ask for meet new international friends, is good idea or not. I really don't know. What should I do? Should I say my feelings immidiately? Or for first step, I just need to learn her phone number? Because I don't know American girls. I am afraid. If she say "I am married" or "I will call police, you annoyed me!" or something like that, what can I do?
Can you help me please?
