We're in the bookshop; it's fairly quiet, just a few people milling around wondering whether to get involved in the whole Stieg Larsson thing, or just to move quietly on to the scary New Titles. The silence is shattered as a woman manhandles a 4x4 all-weather buggy through the perhaps slightly-deliberately-difficult-to-negotiate entrance. We watch her for a few minutes as she clips the card spinner and the anti-theft device. She manoevres the buggy into position, conveniently blocking both egress and entry to all other customers. She asks 'Do you sell lunchboxes?'
