It's a bit odd for sure. I have heard of folks doing that before. It is a kind of weird, nerdy way of trying to connect with someone.
I don't think they mean to offend, but, you know, they do tend to offend.
I do think that folks who do that are most often very very harmless.
The real, deep, racists who are the real problem, they would never try to reach out to a person like that, in that awkward way. They would more stay silent, but live in some real hatred in their heart.
I doubt that woman had any of that toward you.
There is a comedian who has a routine, about her mom doing that...to every single person she meets. And how embarrassed she gets when her mom does that.
