Do girls ever act disinterested on your initial approach as a shit test?

I was at a bar last night with a girl who was locking eyes with me hard that I’ve bantered with a few times in class before. Gave me IOIs in sober settings, touched my chest and I really don’t know her well.

Then I approach and she seems totally uninterested.

My approach wasn’t great, didn’t hold great eye contact as I came up. Do girls shit test with disinterest? Or is it disinterest?
