Careless, careless...

From The Evening Standard:

Traders today told of their terror after a fire swept through Camden's historic Stables Market.

More than 600 shoppers and diners were evacuated from the tourist hotspot at 7.45pm last night as thick black smoke poured into the cobbled lane and rose into a 50ft black plume visible from miles around.

More than 70 firefighters from across London spent several hours at the scene off Chalk Farm Road fighting the flames and removing high-pressure gas bottles – used by surrounding street food stalls – from the area...

The Stables Market, and a swathe of the surrounding area, was sold off by its owners, which included restaurant tycoon Richard Caring, to an unnamed Middle Eastern investor in March this year for £400 million.

The market, the site of a 19th century former stables and horse hospital and where singer Amy Winehouse was a regular shopper, is one of London's best-known tourist destinations, attracting about 40 million visitors a year to its 700 clothes, crafts and antiques stalls.

As a separate issue, that works out at £10 per visitor or £500,000 per tenant.
