I once had an argument with someone in a call centre about using non-standard phonetics. I was in an obstinate mood, and it amused me.
Call centre: "So your code is Apple Mum Sugar Sixty"
Me: "Do you mean Alpha, Mike, Sierra, Six, Zero?"
"Uh, uuhhh, is that Apple Apple...."
"Let me help you: Alpha, Mike..." Etc
I kept it going for quite sometime before she finally gave up and copied what I was saying.
