Extract from Let Me Tell You About Madrid.

Those of us living in fear of disaster may find comfort here, where items for seemingly every eventuality, no matter how grave or unlikely, are available. There is rope, string and webbing; leather and tools; brushes, waterproofs and boots. The less apocalyptic-minded may also note slippers, key rings, and deck chair and awning fabric. Be sure to peer into the back where items of ancient provenance are piled on dusty shelves. Just next door is Caramelos Paco, a madly overstocked sweetshop, probably best avoided by anyone with small children.
