A rose, by any other name, would beat people senseless for not being able to spell "Rose"
Today I am going to talk about names. Names are a tricky thing in this day and age, as they come from all over the globe and even your basic names can be spelled in new and terrifying ways. My name is Meagan. It's not the most common way to spell it, but it's not far off the mark.

And yet.

I have taken to, when I am asked for my name, answering exactly like this:

"Meagan. m, e, **A**, g, a, n."

Past precedent has dictated that unless I deliberately, slowly, empatically emphasize the first A in my name, people will blithely assume it's spelled one of half a dozen other ways. No one has ever gotten it right after I spell it out, and 26 years of that is a long time for no one to ever have gotten it right. So I answer in the above fashion.
And would you believe that 99% of the time, people still spell it 'Megan' after supposedly listening to me, typing the name one letter at a time as I speak them. Just yesterday, I answered at LensCrafters so that an associate could look up my file.
"Meagan. m, e, **A**, g, a, n."
"You're not in our system."
"I assure you I am. It's spelled Me **A** gan."
*checks again, shakes head* "no, you're not in here."
"You're missing the first A."
"Oh, sorry. Meag E n. I'm still not finding you."
"No, g A n" (which she got right back at the beginning!!)

And, by the way, that's what the other 1% do when I spell my name for them. They'll get the "MEA" part correctly, but they'll choose between "GHAN" or "GEN" after that. And it usually takes three rounds of corrections for them to get it right. I just don't understand this. Some people have honestly gone through six different incorrect spellings of my name, with me very carefully spelling it correctly each time, before they get it right. It's like they decide that despite the fact that they're getting it wrong, they'll cycle through every permutation that they can think of before actually listening to me spell my own name.

That automatic "h" bothers me. There's a cadence to the way I spell my name out loud. Three letters, the third one quite emphasized, then three more. m e A; g a n. And yet far too many people stick an H in there. It's like they think, "well, she's got a superfluous letter in there, so we might as well throw a few more in". Seriously, people, if a person is deliberately spelling out their name, listen to them. People with commonly spelled names rarely do that, so there's probably a reason.

(Once, at Chapters, I was trying to order a book and I was shuffled between about five different people altogether, back and forth, and between them they spelled my name (including my last name which adds even more confusion despite only being four letters and one syllable) eight different incorrect ways. I was impressed. One of them spelled it "Meegan Flue".)

I should wear a nametag around my neck. But then, when people inevitably still got it wrong, I'd have to bludgeon them, so unfortunately it's not a practical solution.
