My Shadowrun group at the time was pretty large (about 20 players), and this one night we had a new guy. I don't remember why, but the GM decided he didn't like the guy, who was sitting literally next to him.
So 20 of us are prowling around the mid-section of this skyscraper in Hawaii (some of you may remember the name of the adventure), and naturally, we didn't stay under the business' security for long. So we're on this one floor, and the elevator opens with a ding. The GM asks, "Who was left guarding the elevator?" and the GM said later it was one of the funniest things he'd ever seen 19 heads turn in unison toward the back wall, leaving the newbie shouting, "Oh OH Me! ME!"
5 minutes later, the new guy's character was dead and he was going home. We never saw him again.
