Gatwick airport, London City Airport, Victoria Station, Marylebone Station, trains, London busses, various London cafes, hospital corridor (nobody was around though), Isle of Man airport, Manx busses, Manx cinema, Manx pubs (in one I saw a guy vaping an imitation cigarette, so I got much bolder with the vapour).
The only time I vape with smokers is at the hospital - mainly for the company. They are all interested, most try it and those who do all want one. A non-smoker who runs a chain of casinos etc was VERY interested - if he can keep people inside vaping they will gamble more. He took notes about devices and juices.
