"Do you have a boyfriend?"
This seems like generic questions from an AFC, but if you're confident with it they will giggle and know you asked her that question because you like her. Look at her in a cheeky smirk and the attraction can go go insane..
Read up on "Qualification" if you want to ask some type of questions which makes her invest.
For example,
you- "I hate girls that get drunk every weekend, What do you do with your weekends?"
This will make her tell you what you want to hear (seek your approval) and will cause attraction,
her - " I hate those girls too, last week I went rock climbing bla bla"
Get it?
I just had a quick Google, this should help:

Generally, I wouldn't mess with girls with my job but that's just me when I could just pull them outside of work hours and dont have to worry about my boss catching me
