Uh...all of them? ¯\_(ツ)_/¯

I used to work with a 'floor supervisor' who vaped excessively and obnoxiously. He had one of those things that made vapor like a space shuttle launch too. When he was talking during conference calls or presentations, rapt attention and respect were demanded. When anyone else was presenting, *whoosh*, big cloud of vapor, right in front of the screen, right in the presenter's face. It looked like the building was on fire ten minutes in. Opening the door was like getting out of a car that's been hotboxed. That guy was a douche.
