Hope springs eternal in the human breast...

yet there are limits. And the guy who parked this huge yellow sewage water tanker (5,700 gallons, good area, best vintage) with 'for sale' signs stuck to it was surely pushing his luck.

OK, on closer inspection the tanker turns out to be brand new, fresh from the factory. And no doubt sewage water tankers are bought and sold like everything else. But surely not by casual roadside advertisement, like some clapped out Ford Cortina (MOT failure, £150). It's hard to imagine someone, say, walking to the mosque, prayer mat under his oxter, happening to spot the yellow monster with its sale signs and thinking: Hey, only this morning I was saying to my wife over breakfast, what we really need is a decent new sewage truck. It's not going to happen, is it?
Thinking about it, some readers might be unfamiliar with sewage water trucks. They're not something you see too often in most cities. But Doha does a special line in isolated buildings, not connected to mains water or sewerage systems. It has something to do with planning, or the lack of it. Such buildings are serviced regularly by drinking water delivery trucks and sewage water removal trucks. Ideally not on the same day, and not with the same tanker.

I suppose it could be presumptuous of me to assume none of my readers is interested in making an offer. It is quite a beautiful machine, in its way and might very well appeal to a collector somewhere. If so, the number, which is already public domain and so can be repeated here, is +974 55022771.
