Thoughts on if she is a shy/introverted person or just doesn't want to speak?

Here are a number of scenarios:

1. Whenever I Stared at her, she looked back for 1-2 secs before looking away. (P. S. I never smile for some reason & she might be aware that I'm into her).

2. Whenever I'm standing at the bar with a friend. She sometimes comes and stands at the corner (1 meter or less from me, maybe that's her normal preferred spot) & looks at the crowd but doesn't look at me but is aware that I'm looking at her. (The reason I know she's aware of me because one time my drink was missing and was trying to get my server's attention and she tapped my server's shoulder to get the server's attention for me)

3. She normally looks like a quiet 'introvert' person & can tell she comfortable speaking to her fellow work members & Whenever she is serving people she looks at them & has few secs talk to them. (Maybe, about the order something, I don't know).

4. I was only served by her a few times & both times she directly looks into my eyes without smile (I think, it's very normal). I speak to every server of that club but bit imtidiate to speak to her.

5. She mostly hangout with girl mates but not just a guy buddy on her own. (As far as I've noticed and guessed)

I can speak to other girls and multiple girls showed interest in me last week to talk and dance but I declined, not sure that has anything to do with it. (I can't be that bad of a person, am I?)
