Thank you for all the enlightening comments, ladies, as well as for providing your shared experiences.
I guess what bothered me the most about being referred to in masculine terms during some of these encounters was that the SA's could have at least given me the benefit of the doubt, and that just maybe, I was simply a mannish-looking woman, of whom there are plenty around. I just don't think that I looked that overtly masculine i.e. virtually no evidence of a 5 o'clock shadow, trimmed and slightly shaped eyebrows, heavy make up - but not to the point of being theatrical or drag queenish etc. - yet they went straight there. And no, it wasn't that old standby - a prominent Adam's apple - as mine is quite understated.
I'm still wracking my brain as to what the overriding tip-off was that caused these SA's to refer to me in male terms with such certainty. Clearly, they did not fear running the risk that perhaps - just perhaps - I might actually have been a mannish-looking GG who could have been highly offended by being referred to in those terms.
