The number includes food and drinking places, so if you did not want that included in the total, it comes down to just a tad under $4 trillion. I don't see where they disclose the number of stores associated with those revenue amounts, though.
The History Learning Site, 17 Mar 2015. 16 Aug 2016. The Great Fire of London of September 1666 was one of the most famous incidents in Stuart England. It was the second tragedy to hit the city in the space of 12 months. Just as the city was recovering from the Great Plague, the inhabitants had to flee the city once again â this time not as a result of a disease, but the result of as human accident.
London had thousands of coal fires. It is next to a river. The result of the former was a lot of smoke and of the latter a lot of fog. The smoke got mixed with the fog, creating 'smog', and trapped by temperature inversion. Result: impenetrable fogs which killed, or hastened the deaths of, thousands, most notably in the Great Smog of 1952.
