I AM guilty of messing with adult minds. I've been addressed as Ma'am while in the mens room, I've posted the incident before but here it is for all the newbies. This happend a year ago, when I first started wearing kilts.

I was in the mens room today washing my hands.(I was wearing a workmans UK).My back was to the door when it started opening, then someone said "Oh, excuse me!" and left before I could say anything. About thirty seconds later it opened a little and the same person said"Ma'am this is the mensroom". That got my attention and I glanced over at the stalls.Nope, I was alone.So I said "theres no women in here." The only reply I got was the door shutting. The whole thing took only about a minute. I never did see his face and by the time I got my hands dry and left he was gone.I could tell from the tone of his voice that it wasn't just someone messing with me.
