Those E-cigs give off water vapor. Folks are complaining about water vapor!
Never ceases to amaze me how people will act all smoked out when there is no smoke. Friend of mine gets on the city bus and puts his pipe in his mouth. People start to cough, wave hands and complain about his pipe.....which is unlit and giving off no smoke. He points this out and they usually get even more pissed than if he really were smoking.
