Hey man, I know you're gonna hate this, but I will start off with a little preachin'... You should not mess around at work, it could complicate your life in ways you don't wanna know... been there, done that... Sermon over

Now for the advice...
1. What you talk about makes little difference... I would observe the Mystery Method sequence of Attraction, Comfort, Seduction... Right now you are barely scratching Attraction, so before you establish that, I would stay away from the deep stuff... Comfort w/o Attraction = a trip to LJBF land... not where you wanna go...
2. Does she have a boyfriend? Again, if you play your cards right, it shouldn't matter... By the time you push things through seduction, if a boyfriend exists, she will either tell you to stop because of the boyfriend and mean it, tell you to stop because of the boyfriend and mean it as a plausible deniability or completely keep it off the table until after the deed is done... If there's no boyfriend, then good for you... I can only asume from your story that she's in her early twenties, and we all know how solid relationships are at this age...
3. My advice is to try and meet her outside of work environment for several reasons... Co-workers may see you and she can develop ASD (who wants to be the slut of the restaurant?), there's little time for you to work your magic and as enticing as a cold storage room quickie may seem, it could result in both of you being fired... and there's always that little thing called sexual harassment
I hope you will find my ideas worthwhile... Let me know how that turns out... bye!
