Jennifer,
I think it's pretty awesome that you (and others) get out & about during the normal course of everyday life.
And yes, odds are one will be treated with at least some typical courtesy & respect when face-to-face.
However...
If one is in some sort of "business" setting, whether it be retail, or a restaurant, or whatever, then yes, most if not all staff should & probably will serve a CD as they would any other non-CD customer.
But after that CD is gone? Who knows what happens. And you'll never know. The professional might very well run to the bathroom & literally vomit. Or, perhaps simply chat with one of his/her associates... "Yeah, had some freakin' dude wearing a wig & skirt come in earlier today. I was like, WTF?? Unfortunately I was the only one around at the time, so I had to help him/her/it, whatever that thing was. And their nails were even painted? Really? Totally creeped me out, I'm telling you. I really hope I don't have to experience that ever again."
Is that what one would consider "acceptance"?
And remember, this is in a business environment, of sorts. Outside of that, anything goes, really. I've had some awesome experiences, myself -- as well as some not so great ones. I'm betting many of us here have. It's not all puppies & rainbows & glitter out there when it comes to this whole "trans thing." You realize that even physical violence can occur in some circumstances, right? And yes, some are even *murdered* because of this -- look it up, it's true.
Not saying this is likely to happen, but it can & does.
Again, does that sound like "acceptance" to anyone? Honestly?
In any event, this obviously shouldn't stop anyone from getting out there or anything. Have fun with it, enjoy yourself. But they do need to mindful of where they are, and who they might be around, and how might they be able to handle themselves in certain situations.
