I live in Europe and I tend to get a lot of odd looks when I use my 510. So far no one on the street has said anything but I notice the looks. Europe is a lot more smoker friendly than the states, no non-smoker would ever berate you on the street (like happened to me more than once in the US) but they don't seem to have seen too much of the e-cig yet.
At work at my computer I had just let out a big puff of vape when a new employee happened to walk by and asked if I waited for the boss to leave and then smoked. So I explained what it was and took it apart and she was like "thank god, I thought you were smoking crack"

No one has said anything to me yet but I haven't pushed it either. I mean, I haven't vaped where they don't allow smoking or anything like that. I just don't want to hear it.
