I am a traveling manager for a regional chain of tobacco shops, and to me it seems that there is a bit more snobbery with vipers vs traditional tobacco users. However, this also varies by demographic. In our stores near college campuses it seems to be more prevelant. However, with our stores, as well as many others I have visited, we seem to focus more on both educating and learning from others. If you are experiencing snobbery, try to find a new store.
On a side note.... yes after 5 years I am back from the dead...can't believe my last post was in 09 lol
