The voice on the other end of the call was angry already.
I opened the customer's file, and confirmed the device they were having issues with, "Did the product get damp at any point?"
There was a slosh and a pause before the customer responded with a shifty, "No."
I suppressed a sigh, "Have you tried rebooting the product?"
They said yes, then quickly claimed their auto-dancer shoes were mysteriously working again, before hanging up.
