After reading through copious posts, I was under the impression I would need to explain what an e-cig was wherever I used one. Not at all the case in Dover, NH. I went to a jewelry store to sell some gold bullion and asked the manager if I could use my "vaporizer" and she said "go ahead, it won't bother me". And then she asked me where I got it and ended up giving her a website for an inexpensive 510 kit so she could get one for a smoker friend of hers. Went to a pub afterward and asked the bartender if I could use my PV and she said, "of course!". Then a customer next to me asked me how "it" was working out for me. Seems like what e-cigs are and that they are a viable and relatively safe alternative to smoking has really become common knowledge in the service industry around here. Awesome.
