Just tell me the letters.

I realize that in the pantheon of annoyances, this is probably one of the lesser irritants, however it makes me bananas when someone spells out their name thusly:

"'S' as in Sam, 'H' as in hello, 'A' as in apple, 'M' as in marshmallow, 'R' as in rutabaga, 'A' as in apricot, 'G' as in garbage pail".

That totally flummoxes me as the listener. And when I ask for the letters only please, my request seems to then flummox the speller-outer.

I mean, I get it about how 't' and 'c' can be confused, or 't', 'c', and 'd'. But really, if you feel obligated to say "geeeee as in gasoline" it just sound complicated.

Ok. I am done.

For now.
