I had a call a few months ago which went something like this: "Hello" "Do you mend computers?" (big voice, possible senior military and retired) "Yes, what can I do to help?" "Just moved here from the south, plugged it all in and now the damn thing won't work" "Not a problem (thinks - money for old rope, this one). Where are you?" "In Leicester" (Gives me the address). "OK - I will be in Leicester this afternoon so I will call in at about 3 if that is OK?" "Fifteen hundred hours - right, I will be here. Cheerio." I turn up almost on time and am ushered into a nice sort of study room in a brand new house and I have a look at the desktop PC he has set up. I turn round and walk out of the room and to the front door without saying anything. "Oi - where are you going?" "Back in a moment" says I, and goes to the car to fetch a kettle cable. Watched by the Colonel, I connect the power lead to the PC, check the rest of the cables are where they should be and turn it on - and it all works just fine. "Well that was pretty silly of me" he says, "How much do I owe you?" "Nothing" I say, "I was almost next door and it was only a power cable and I have buckets of them". "Thank you very very much" says the Colonel as he ushers me off the premises, "Are you sure I don't owe you anything?" "Not at all" I say, kicking myself. In the event it was the right thing to do as a few weeks ago the Colonel phoned and orderd a new high spec system, a decent multifunction printer and asked for help setting up his wireless router. Sometimes these things take time to come home to roost!
