I had arrived in Khari Baoli, Asia&rsquos largest spice market, in time to watch the start of one of the world&rsquos greatest pieces of street theatre. The flower sellers, as always, opened the show, slashing open their vast sacks and letting a tricolour of marigold, jasmine and rose tumble out on to the street. Then, as the spice vendors&rsquo shutters flew up and hundreds of small pyramids of dried fruit, nuts and spices appeared, a cast of thousands began to emerge. An army of sweepers cleared mountains of debris from the previous day and threw up clouds of dust with their twiggy brooms while chai wallahs crouched over their stoves, hurrying to make the spicy brew that would get the market moving. Portly spice merchants started to stroll in from their homes in the suburbs, tended to their pujas, garlanded portraits of their ancestors and prayed fervently for a good day&rsquos trading. Scrawny porters dragged aching limbs from sleep. The lucky ones were curled up on the handcarts that served as both home and workplace the less fortunate were waking up on the pavement or the roof of Gadodia Market. Most wore long shirts and lungis, with checked scarves flung over their shoulders, ready to wipe away sweat and cushion heavy loads. As the tea slowly worked its magic and traders turned their attention to the day&rsquos business, the porters loaded up their carts or heads with sacks and boxes. For the rest of the day, they would race back and forth, delivering goods to shops, trucks and railway stations, oblivious to anyone who got in their way. (A common souvenir of a trip to Old Delhi is a set of bruises from collisions with market porters.) Later, when the work had run out or complete exhaustion taken over, they would wash themselves and their clothes at standpipes, then eat their only meal &mdash for most of the day they are powered by gutkha &mdash and perhaps smoke a bidi, the tiny hand-rolled fast track to emphysema and lung cancer. On a good day there might be a card game or a few swigs of cheap rum.
