persoanlly, a general rule of thumb for me is if smoking isnt permitted (within reason) or its generally taboo to smoke in a area, I dont
vape in a area. IE, I'll vape in a bar (and if asked ot stop, will do so), but I wont vape in a grocery or electronics store. In a park? you bet. In the car? sure. In a box with a fox? you betcha.
Airports I would perosnalyl avoid, but only because airports are so strict nowadays. Hotels are iffy too, because if the hotel considers
vaping as smoking and you vape in a non smoking room, you can potentially see a rather large unwelcome increase in your rooms fees.
Resturaunts I'd stealth vape simply for the courtesy of other patrons.
but, thats me and my paranoid self ^^
