It must be a very special diagnostic sequence that manages to progress so far without alerting the techie to elements like that.
Not really. If you are on a computer or internet helpdesk, then you probably start with certain assumptions about the caller: that they have a computer, and that they have (or want to have) internet.
I would imagine (as a random example) that a plumber call out service don't usually start by asking "do you have any water pipes" if you ring them...
