personally ive been asked to stop only like 5 times, and the reason was always the same, and made alot of sense, granted it was always in bars the manager/person in charge walks up and asks me to go outside to vape, they explain their understanding that its not harmful but do not wish for someone to see the vapor and think its ok to smoke inside. other than that alot of places are actually ok with it, one manager told me he liked it because if people saw they could vape inside they may turn the way of e-cigs and then he wouldn't have to deal with so many cigarette butts, and his patrons having smokers cough at the bar.
