When I worked at Dillard's we had a customer who was a CDer. I don't know at what point on the "trans" spectrum she was, I called her "she" because she wore women's clothing, though she didn't wear makeup or any other appearance altering accessories. Anyway, she would come in and try on formal dresses, she was a regular and sales associates would scramble to help her because it was well known she always purchased a few items. At one point, the store manager told us she was no longer allowed to try on clothes in the women's dressing rooms. Our dressing rooms had no shared hallway, they each had their own door that faced the sales floor. No contact with any other customers would ever accidentally occur. We actually had to carry the items that she wanted to try on to the men's dressing rooms for her to try on there. The sales associates actually fought against this policy on the basis that we would be offending a good customer without a legitimate reason. It was really embarrassing for her and for us. She stopped coming in after a while. This was about seven years ago. When the bathroom bills started, I was reminded of it and how ridiculous it seemed even then. Just an aside, as a gg, I would prefer a mtf trans person use the same bathroom as me because as a woman, I'd be scared of using a men's room. I don't want people to get hurt and that seems more likely to happen in a men's room. That could just be my own prejudicial thinking though. That may have come out wrong, but men's rooms seem dirty and men, in my experience, don't always know how to behave when there's a lady alone and they're in a group.
