The Problem
I'm 17 with a lame underpaid retail job and I stick at it because I like a hot coworker,8.5, who is 2-3 years older than me. I need help getting her.
Interactions Before I Knew What Game Was
I met her before I knew about game so I have probably fucked things up already

But here is the extent of our interactions so far. We normally just say hi to each other and smile and she normally asks when I am next in. Our biggest interaction was one shift when it was real boring and we both hung out by the computer for an hour. I found out she was a gamer, a common interest, so we bonded over that and I teased her over owning an xbox not a ps3. She revealed that she had had a ps3 but her ex had taken it. We mainly talked about what you guys called fluff, although I do recall holding strong eye contact whilst she was using the computer (She turned away and looked at me when we talked).
If you want more details on anything, my memory is superb, please ask!
My Game Knowledge To Date
I have just heard about game since coming on holiday after googling how to get girls (I have never kissed a girl or had a girlfriend, but I am average looking, just 0 game and was shy, but I am a shop assistant now so the fear of aproach is not there).
I have now read the game, magic bullet, the art of seduction and what everybody is saying.
So I know the basics now. I'm pretty sure I was friendzoned due to me not saying anything sexual (I was hiding my interest like an AFC).
The Plan
I am going to go back to work ask her how her new thing was (She was real excited about it and will definitely remember). I am then expecting her to ask me about my holiday to which I will reply and fit in that I saw this movie that I know she will like and I expect her to say something along the lines I want to see it/that sounds good. The plan from there is to ask her if she wants to see it with me and maybe grab a bite to eat before or after the film after work one day.
The Help I Need
It will almost definetly be as friends, even a newbie like me can tell from what I have written. I know the basic game but attraction eludes me how could I create some before asking her? Also I have no idea if she will say yes, she could think I am asking her on a date which I am but I feel like with what I have written she may freak. I dunno I overanalyse a lot (I am quite quiet at work, but everyone knows me).
Please give me any and all advice! Sorry for the wall of text and thanks for any help!
