Part of my job is to find out what has actually failed whilst on the phone

I used to do that in IT.

When I worked in IT I'd get people saying "the keyboard's broken",
so I'd take a spare keyboard along to investigate, only to find
out that actually the /computer/ wasn't working.

Or "the computer's not working", while pointing at the monitor.
