Search Results: too pretty to work with him

I'll give you an example: I was out working, doing food deliveries. I went to a restaurant to pick up an order. I had been there once before. The girl working behind the counter was really pretty. She was the same one who was working there last time I came. The first time I saw her, I was kind of in shock and awe of her beauty; so I didn't say anything, of course. Just made the transaction and got out.
This time -- the second time -- I remembered her (of course; how could you forget an angel like that?); but I had had enough time to process her existence and emotionally deal with it, and I had already grown a cold heart about her. (Because that is my modus operandus: noticing beautiful girls and growing a cold heart. I'm very emo.)

So I had my poker face on (which is what I wear to ensure that a hot girl doesn't think that I like her.) Unfortunately, my poker face is actually a Resting Bitch Face. So it may come off as a bit unfriendly. Maybe she might have even thought I was scowling at her. (I wasn't, really; I was just trying to cope with my internal angst. And I guess that ends up showing on the outside. The darkness in my heart and the pain in my soul.). But truthfully, I don't hate her. Not at all. I just hate myself for not knowing what to say to a woman.

Anyway, I noticed that she seemed a bit cold and rigid herself. So maybe she was mirroring the energy that I was giving off towards her. I was a bit surprised, though, and kind of embarrassed. I felt bad, because I thought that maybe I had taken it too far and come off as a bit TOO intense. I never wanted to come off as mean or rude. Just "not interested," that's all. All I wanted was to hide and camouflage my attraction and infatuation with her.

So, what do you guys think? Did she know that I liked her? Did she see through the mask, and was she annoyed that I was hiding it?
Or did my deceptive maneuver work (too well) and did she actually think that I disliked her?
