At this conference center there was an alcove near the bathrooms with a door labeled “ACCESSIBLE VOID”. Some sort of cabling or piping access I figured. Then I saw the door open, and an attendee emerged, adjusting their lanyard.
I approached them, “Hi, I saw you just came out of the void door, what’s in there?”
“Introvert BOF. Ten minutes floating in nullspace and i’m good for another conversation or two. I wish all conferences had proper voids, quiet rooms don’t compare.”
