Before you say "don't shit where you eat" consider that this is just a part time bar job whilst I'm studying, and therefore I'm not interested in hearing such advice, as I will leave this job eventually anyways. Instead, my main struggle is fear of rejection given that I would have to see the girl often after being rejected and this could be pretty uncomfortable.

This chick seems to be giving potential IOI's - I have caught her looking at me a couple times and she's given me cues to invite her to stuff or spend time together. I even slept over in her bed with her after after work drinks one night (Ik i'm a bitch for not trying to f close but that's only because this coworker situation gives me unusual fear).
