Did I Read Her Eye Contact Response Correctly

I was at the library getting a book yesterday. There are two rather attractive females working there. I wouldn't mind getting with either of them. One has some tats and would be a good #2 (mistress), one is feminine.

I've spoken to Feminine before. She's cute, we flirt but since she's at work, it's not a long interaction.

I've flirted with #2 often but same deal. I also have my daughter with me on occasion so I try to keep this to a minimum when she's with me.

Anyway, yesterday something came up I was trying to figure out what it meant (if it follows a "rule") regarding eye contact. I checked out these threads:

But none of them answered my question.

Feminine was walking around, holding a paper. I said hi as I usually do when I see her. This time, rather than smiling or engaging in some talk (as she almost always does) she waved, said "hi jbird" back, but while she did so, she turned her head to the right. I chalked this up to her being at work and stressed, and #2's counter opened up so I went to her to check out.

In a social situation, Feminine's response tends to mean she considers you inferior. I am not sure if that means the same thing when she is working. This was the first time she did this and it's the opposite of every other interaction.

I'm curious to know what this means for other chicks I approach when I see them working.
