Although i get the occasional "hey, no smoking inside" joke, No one has issues with it. I was once accused of smoking indoors (early on in my vaping) after the boss smelled smoke, he confronted me and was a little taken aback when i said i have not smoked in over a year.(the culprit admitted to me in confidence afterwards lol)
This is because regardless of being "allowed" to vape, i try to keep it on the D.L. so as not to draw unneeded attention to it. He appologized and told me he had no problem with it as long as fire was not involved. Just recently he saw me vaping and said "wow, no cancer sticks still? very good"
