I am not shy at all. I've been vaping in public from the beginning, starting with cigalikes and on up to mods the size of a Provari or MVP with a tank. I carry my vaping device with me everywhere, usually in a front pants pocket. I occassionally have a vape while in the grocery or department store, occassionally at a bar or restuarant (depending upon the establishment's wishes), concerts & festivals, just about everywhere.
I routinely vape in the cinema, however I do it discreetly and stealth-fashion. I always sit in the back row away from other viewers, and only after the movie has started and the ceiling lights are out. I do the double inhale technique to hide the vapor.
Vaping is not yet widespread in my city. I have yet to see another vapor "in the wild", however I have at our local vape store. I don't get any strange looks while vaping in public. In fact, the few times that people have taken notice they have asked what it is that I'm using, where did I get it, how does it work, and how much does it cost. I often have business cards of my local vape shop and will offer them a card.
I've only been asked to "stop smoking" once. A customer was eating his meal in a primarily take-out Chinese restaurant while I was waiting for my carry-out order. He was seated at a table at least 20 feet away from me and I was standing at the exit door. I took a couple of vapes and he saw me. He asked that I stop smoking as he was allergic to smoke. I politely said it's not smoke, but water vapor from an electronic cigarette. He then appologized and returned to finishing his meal, and I out of respect to his wishes I did not vape any more.
