Those automated telephone systems that call us up at random and urge 'please listen carefully to the following announcement', aren't they irritating? Who takes such things seriously? And when they do, how much of a ride do they then get taken for? It is always wise to be on your guard against scams, marketing ploys and folk who may be making false promises. But that doesn't mean you should be overly defensive this weekend. Something that looks a little dodgy at first, may prove harmless and helpful.
