Many of the Londoners who want to interact with other people like they are other human beings have given up on the Big Smoke and moved to Bristol.
Maybe it helps that Bristol doesn't have a tube system, or even a bus system anyone uses. By foot, by bicycle, light rail, skateboard or supermarket trolley (depending on route and quantity of strong cider consumed) are acceptable forms of transport. Also, many a Bristolian considers it acceptable to spark up a 'jazz cigarette' as they stroll down the pavement in most parts of the city.
