I think I can get behind the HUACA mantra.

But whenever I see "hang up", I picture callers literally hanging up the phone on people in mid-sentence. What's the etiquette? What if the CSR thinks they can "fix" the problem after the hangup?

Am I looking to inform the CSR that I'm going to hang up, and instruct them not to do anything else on this file? Or literally just go CLICK?

Please teach me the ways of HUACA.
