I was speaking to a custy on the phone and had to get his credit card and billing info so I began by asking him his name and address and he told me.
I started verifying the spelling of his first and last names back to him saying, "So, to verify, I have A-l-l-e-n G-u-t-h-r-i-e.
Custy immediately bursts in to say, "No, it's E-l-l-e-n. Ellen."
Me: stunned silence and major embarrassment
Custy: E-l-l-e-n. (Emphasis on the first E.)
Smooth, Susan. No apology, no nothing. Just "Oh".
