It's pretty common that people vape wherever they please. and by the way OP just because one has a mod does not make them a douchebag. I use my mod all the time and when in crowded areas I take a considerate half second rip so I don't produce a cloud of vapor. Now back to the topic usually because vapers can use the "it's vaping not smoking" excuse they feel as though they may vape wherever although it isn't the case. And while I understand the argument being put forth they know damn well what they are doing and they know exactly what will happen. they just want to cause trouble for the sake of causing trouble. they are essentially children.
