I have been told no. Here's a couple examples.
Last year in Australia went to a Dangerfield store dressed. Spent about an hour with Amelia.
Went back a week later as the guy me. Amelia was at the desk. I asked her if another associate was working. She didn't know it was me.
Was in a local Savers. A young woman came up to me and said I looked good, had great legs, and should stick to short dresses (which I tend to do). We talked for about 5 minutes.
A week later, browsing in boy mode. I see her, and decide to walk up to her. I made mention of something we had talked about. She had no idea I was the same person. I even asked her about it.
I was in Vegas, in a Ted Baker store, and asked the SA if they had a certain dress, and showed her a dress that I was wearing (what happens in Vegas....). She asked when my wife tried it on. I told her it wasn't my wife, it was me.
Also, I was walking into DSW and walking out was a woman who knows me (99% sure it was her but I looked away to try to avoid detection). She has never said anything. Fortunately, I didn't blurt out "hi Erin"....
