I think the important bit here that maybe I didn't make clear is that, at least in the context of men flirting with women, sometimes women are kind and polite without actually being comfortable (social conditioning), which many men incorrectly take as a sign of interest.
I agree that if you're charming and fun, flirting with strangers is pretty straightforward, and I especially agree with the point about getting to know people over a longer period of time before trying to gauge potential interest. Worst case, you get a cute friend!
