<human>: Could you distill the essence of the text into 1-3 sentences?

first time post in here, using a throwaway so ill try to check this account as often as I can. I own a small business and had a customer come in today I've never seen. She was beautiful, very friendly and nice. She dropped off her mobile device for us to repair. We talked a little bit while I took down her info into our system, I asked her how the problem happened, threw in some witty banter to make her laugh, and she went on her way. 

I don't run into pretty girls often in my line of work, and its entirely possible, shes way out of my league, or has a boyfriend. But I'm thinking of asking her out... the questions I have are how do I do it? and should I do it?     

The customer lives a town away, and will likely be back tomorrow to pick up her device. The thing is, I may not be the worker who deals with her when she comes in. (I could be working on another job when she comes in to pick up, or be out on lunch break). Even if I was there, I'm not sure if its unprofessional to ask out a customer. She seemed friendly, but I wouldn't want to alienate a customer and get bad word of mouth. I can't be fired since i own the company, but I also don't wanna be known as the creepy shop owner around town. 

She technically gave me her cell phone number when she dropped off, but I'd imagine it being sort of a ethical violation to call her to ask her out or send her a text. I checked quickly and found she is on facebook, but I'm not sure if adding her after she picks up would be creepy or not.

Next, is she even single? Obviously all this worry is for nothing if shes with someone else, any suggestion as how I can find out? her facebook is entirely private, I can't even see how old she is, haha. 

Thoughts? Suggestions? Advice?
