<human>: Can you summarize the given text in a few sentences?

I was at work today, and this really cute girl walked in to send a fax. She needed some help getting the machine to do what it needed to, and i offered to help her. During the course of what i admittedly dragged out into what must have been a 45 minute transaction, I got to talking to her, and she seemed super interesting. I was really flirting with her, and I think she was even flirting back with me during the course of the whole ordeal. So, where it gets creepy, is that while i'm not the kind of guy to have the kind of courage and confidence in myself to just ask a girl out on the spot, I have her number. It was written on this fax cover sheet she filled out, and while she took it with her, i remembered the number. Enough to write it down. I want to call her and ask her to coffee or something, I just know this could be a super sketchy move. Personally if it was the other way around, and someone thought I was good looking enough to literally steal my number and call me, I think I'd be flattered as hell. 
So i guess what I'm asking is, after reading that, do you think i should call her or not?
<bot>: met a girl at work, stole her number off a fax cover sheet, want to call her but not sure if it's a super-creep show move. Suggestions?
