What this a stupid way to approach a women ?

I feel stupid when I look back at how I a girl behind the cash register phone number. She was getting my change and she turned around and I asked her name and I told her mind. Than asked was she from around here. (Of course she was idiot) than I just asked right out would she like to text sometime. And she said yeah let me see you phone. I feel like I was shy and could have approached better With different choice of words.
