I vote with you, except in the cases of co-workers that deliberately wait to pass gas until the elevator doors shut.
Ha! It seems that I often get on an empty elevator just after the "phantom farter" has departed. I'm on the top floor, so as the elevator goes down and someone else gets on and wrinkles their nose, I want to shout, "but I didn't do it! I didn't do it!"
LOL-- phantom pharter. ..
