I haven't seen anybody get offended necessarily yet. I've had some people ask me about my Blu, mostly smokers interested in trying it and saving money but not quite sure if they want to take the "plunge" yet. However, I was at a flea market on saturday that has an indoor and outdoor part, and some guy gave me a dirty look when he saw me exhaling the vapor. He didn't say anything to me, just kept on walking. I've vaped in Lowes and Wal Mart, and nobody said anything. I think the blu/green/anything other than red LED helps a lot. I imagine if I had a red LED on my e-cig people might be more inclined to think it's a real one and complain though. An ex-smoking coworker saw me fiddling with my PCC and asked me about it. She didn't seem interested in trying it, but she was interested in the information, and she asked me how it was working for me. I haven't completely quit smoking, but at the most I'll have 3 or 4 cigarettes a day on weekends when I'm with my girlfriend who is doing the same thing but not having as much luck on cutting back as I've had. Before the e-cig she was going thru 2-3 packs a day. Now she's down to about 1 pack a day. I've been trying to encourage her to cut back more. I guess it just takes some time. Anyway, the coworker that asked about it was happy to know that it's helping me cut back like crazy. No explicit negativity from anybody yet. My mom is happy that I'm barely smoking at all now. She's okay with me doing it in the house but doesn't like seeing the vapor come out of my mouth.
