Holy crap - NO, it is NOT okay to do this! What an inconsiderate woman to walk up to a stranger and say such things.
I'm so sorry you had to deal with this. Really reminds me that some people never escape the 2nd grade school yard, I'm just so stunned that an adult would do that. I am sure she thought she was doing you a favor or something, which is just mind-boggling. I just cannot imagine.
I'm sure you were even more stunned that I am. Please, just try and brush it off. People like that truly have something wrong with them - how incredibly self-righteous.
