Further to previous posts on this subject, we have been cold-called twice this week by fluorescent-jacketed young men with an identical spiel. They began by saying that they were on the final stages of a survey of houses on the road and went on to speak of benefit entitlements to do with loft insulation. Both were wearing identity badges of some sort, although neither mentioned the name of their company or sponsor. I should have asked, but didn't. Having once again explained that we had no need of his help, I told the second one that I doubted that he'd have any luck in our road as it had already been covered. However, he carried merrily on. Although not it seems any sort of criminal enterprise, this outfit does look dodgy. The reluctance to spell out from the beginning what they were really after, plus the fluorescent jackets on a very sunny afternoon, - which were presumably meant to indicate some form of official or semi-offic1al role - should I suppose be in themselves a warning to the unwary. But they have a damned cheek, and the more often they are told this, it seems to me, the better.
