I worked in a call centre about 10 years ago. one time some old, presumably white, old woman called in and when spelling her name included "N for N****r"
I had too many customers get confused when I asked, "and that is pudenda spelled P as in Papa, U as in Uniform..." customer interrupts, "why are you talking like a radio?"
Had a regular that would spell it in NATO, and said he served in artillery. Heard just fine on his good ear, tinittus was just a low hum.
The police rang my house once, and he told me where I could reach them, and spelled out his name. I started writing his name out, but by the fourth name, I was thinking wtf is going on. This guy was spelling out his name by using names for each letter. A for Alex, B for Bob.
I'm all about that NATO phonetic alphabet - which for some reason rubs certain people answering phones the wrong way.
Can't say I don't have a couple substitutions, though (Zebra instead of Zulu, Sam instead of Sierra, Frank instead of Foxtrot), but it's not like I'm working the radio of an aircraft or something.
Years ago I was on the phone with an airline agent and I had to read out my verification number. When I came to the letter V my brain short circuited and the only word I could think of was "vagina". I sat there in a panic for probably about 10 seconds going "uhhh... uhhh..." before I finally remembered the word "valentine".
I used to have to be on the phones A LOT, and when I was requested to do this I would use the "Pasta Phoenetic" alphabet. You wouldn't believe how many different types of pasta there is!
My eternal gratitude to anyone who can find the old Jonathan Katz stand up bit where he was spelling things out ridiculously to a 411 representative. I must have taped over my old VHS with it.
