I want to share this story with all of you, it definitely made me feel better about the rare time I get misgendered now. My brother is often mistaken for a woman on the phone and in drive-throughs, but we always laugh it off.
So the other day my brother calls to cancel his credit card. The guy on the other end asks security questions, and then goes "um...we can't do this service over the phone, you'll need to go to a branch." Brother (henceforth known as B) goes "well why did you ask my security questions? I said straight up that I wanted to cancel the card and now you say you can't do it?" And the guy goes "well, I tried, but it didn't work." And B goes "so now you're lying to me?"
Bank guy: You'll need to go to a branch and show two pieces of ID.
B: ...why? Tell me, is it my voice? I know it's high. Not convincing enough for you? I answered all my questions, I don't know what further measures I can take!
Bank guy: I'm speaking a woman right now.
B: Well last time I checked, I had f* balls between my legs!
Bank guy: I'm disconnecting the call.
B: Why don't you forward me to your manager?
They did exchange some other colourful pleasantries, but B was too mad to talk to the manager and hung up. So he goes to the branch today (I'm with him and I see this whole thing). He goes to the teller to cancel his card and she says he has to go through the phone. He said "well I tried..." and tells her the story. He said the guy told him he made a note on his file, so she looks it up, and it says "Female called in asking to cancel card."
So the teller calls the credit card people for us, and she must have been talking to the same guy, cause she said twice "well, uh, I can see why you thought that...but...it's not the case." Finally they cancel the card. My brother said "sorry if I came off as rude when I told you the story, I was just mad!" and she says "I'd probably be the same if that happened to me."
I just laughed the whole time. My brother is about a foot taller than I am, he's got a dark beard shadow, and in person, you'd have to be insane to think he was a woman. But voicewise...well, let's just say if he was MTF, he'd have no voice work to do.
