At work I tell customers that I 'go by' my male name. It chops the snake's head off before it can hiss. Before I did that it lead to a lot of mixed reactions when they saw my business card name or read my name badge. A lot of people just find it charming now.
Course, one customer of mine who had to cancel an order (and I was briefed ahead of time by my coworker who canceled it - who informed me that the gentleman kept using my male name and referring to me as she, and said coworker was dumbfounded) returned to re-order and told me "I spoke with your boss..."
No, sir. You spoke to the middle aged white gentleman that I trained for this job. Also, our boss is a woman.
*glare*
I've been told that once I present female I will have to use the ladies room, but that they won't allow me to change my name at work until it's legal. ... even though people can go by nicknames or middle names all they want.
Also apparently passing full time with customers (except when coworkers pound 'him' and 'he' into them) and new employees isn't presenting female enough.
Oh well, all the more contrast there will be when I start wearing makeup and showing chest off.
