While riding the elevator yesterday at the Marriott Philadelphia Towers, where I'm staying for the Pharmaceutical Meeting Planners Forum, I couldn't help but notice a slight problem with elevator etiquette. You know the way people always face toward the door? Well, this elevator opens up on both sides. So when the door opens and people find their back to it, they quickly shuffle around to face the door. Then on the next floor, the same gig happens as it opens on the other side. Those who've ridden it a few times just huddle against the side walls, forced to face each other. For some unknown reason (possibly a lack of sleep), I'm finding this hilarious.
