You think she might be into me?

Basically, there’s a girl who came in a week ago to purchase goods at my work. My coworker was at his desk (directly in front of mine) and the customer was facing me.

As I go to sit at my desk, I look at her and she immediately smiles. I’m shy so I look away right then and there. Need liquid courage for that. So I sit at my desk and I have this weird feeling there is someone staring at me. So I look over and it looks like she is looking thru my coworker and at me. Interesting.

So I do a bit of a conformation of this by getting up and walking by his desk several times. Each time it appears her head is tracking my movement staring at me further. Interesting… I’m thinking she either finds me super attractive or historically hideous (and I’m not a bad looking dude)

So after they leave I ask my coworker, was it me or was she staring me down? He said yeah, she was. I was trying to make eye contact with her but she was looking past me, right at you. Unless you weren’t at your desk. Cool I’m thinking.

She’s coming to pick up said goods tomorrow (my coworkers off day) and we’ve orchestrated that I’ll be the one to deliver the goods. I’m thinking of saying “here’s my card, it has myCELL PHONE NUMBER on it (which it does) so feel free to text me with any questions or comments or anything. Congratulations, I’ll text you tomorrow and make sure everything is okay.”

That way the ball is totally in her court but I’m certainly hinting for more. If she thought I was all that attractive, surely she’d take that as an invitation to pursue a bit. I just want to tread lightly here as the last thing I need is to lose my job.

Tl;dr girl seems interested but is a customer from my company. Need to get opinions and see how to pursue this further without coming off as creepy and losing my job…. Which my manager said he’s totally cool with me doing this.

What y’all think? What would you do here?
