Facey Smiles!

So, a client calls me to get a fax number to a particular department.  I provide it for her.  After a pause, the client says "Oh, I already had it here on this business card.  It was next to this word.. facey smiles."

I'm gonna let that sink in for a minute.

Is the word 'Fax' so overused that the average person no longer recognizes that it is short for Facsimile?  Or am I just acting like a Snobby McKnow-it-All?  Probably a bit of both.

I did pronounce 'facsimile' correctly for her and explained that 'fax' is just an abbreviation of that.  But I gotta tell you, I liked her pronunciation better.  It put a smile on my facey.
