"It's Charlie from the Office"

That's the only identification the caller gave me. I even asked again.  

He was planning on painting his concrete floor and wanted to know how to go about it correctly.

I gave home the details on how to prepare, product to use and how to apply it for the best looking appearance. That was after the first tip we give anyone :  "hire a professional."

I hope things go well for Charlie, whoever he might be.
