Mostly A and occasionally B, and I have yet to experience an uncomfortable encounter with either a stranger or a female SA when I am out shopping as "Leslie".
I would even go so far as to say that those SA's in women's clothing stores who do "read" me - rather than being taken aback by the realization - actually seem to go out of their way at that point to be especially attentive to make my shopping experience with them a pleasant one. And they usually set me up in a fitting room before I even have a chance to ask.
Whether that is a manifestation of some latent protective/nurturing instinct that comes to the surface at that point, or else an unspoken admiration for the effort I have made to perfect my female presentation without appearing like a bad parody of a woman - it's hard to say. Then again, maybe they just see me as an older, better dressed (read "feminine"), and more sophisticated woman than the average mall shopper, and one who looks as if she knows what she wants and is willing to pay accordingly. And for them, that can potentially translate into a good sale and an even better commission if they play their cards right. In the end, it doesn't really matter. I get great service, and they get an easy sale without the grief some GG's will put them through (demanding, difficult to please - the proverbial "bridezillas" ), and everybody wins.
And as for the looks that I get from the GG's that I pass on the street or in the malls - when I first went out in public en femme and had women give me those long, analytical looks they tend to, I used to get paranoid and expected to be "outed" at any moment. Now I'm not so sure, and I think that instead of (or perhaps, despite) being "read" - those looks probably have more to do with analyzing what I am wearing and mentally critiquing the overall "look" that I am aiming for, while subconsciously comparing it to whatever they happen to be wearing at that moment. In other words - simply an example of the old adage that women don't actually dress attractively to impress men, but rather to impress other women .
