I actually had to ask Kerry (one of my favorite SAs) to snip the tag off because it got snagged on the lace fabric, so after I left the fitting rooms, I apologized for staying later, and she said "Don't worry about it, I really love seeing you here!".
Whenever it's been several weeks since I've shopped there, most of the sales girls walk up and say "Hey, it's been a while, it's really nice to see you again", especially Kerry, and I can't help but blush and kind of shyly play it off.
So I'm not sure which seems more probable for their friendliness 1) they're secretly amused and just find my crossdressing pathetically laughable, and they ridicule me as soon as I leave or 2) they're genuinely friendly to me both as a customer and as a person in general.
