I hate it when that happens,
I had a secretary woman phone me to enquire for a carpet clean in their offices she said it was approx 1000sq mtrs so although it was about an 1 1/2hrs away I drove there to give a quote (thinking it would be worth it)
it turned out it was a garage converted into an office, the woman (who introduced herself as the chief secretary during the original phonecall) was secretary for her husband who was a self employed window salesman.
And the carpet was not even 10 sq mtrs, so I initially thought, ok i`ll give them a price to clean it now whilst i`m here (not a complete waste of time, and at least i`d get me petrol money back)
on closer inspection the carpet was carpet tiles and none of them were stuck down,
that was the end of that I`d spent over 3 hrs driving, built my hopes up thinking I was on to a nice little earner,
and in the end earnt nothing and spent £25 on diesel :
