Not a big worry? A drop in the ocean? Are you kidding?!! The NHS sends hundreds of millions of letters to patients each year - if each one of those includes 2 extra sheets of A4 which tell the patient zilch, then it's costing the taxpayer 3 times what it should in NHS paper costs (not to mention ink, electricity and office workers' time to collate them). We used to cost out paper at 1p per sheet, WAY back when, and costs haven't gone down! Do the sums, for crying out loud. Even at 1980 prices, 100,000,000 sheets at 1p = £100,000. Now treble it. Drop in the ocean, my beautifully-proportioned backside.
