I wonder... (#2)

Eight years ago, when we were in the hospital giving birth to my first daughter, I noticed that all of the electrical outlets were mounted "upside-down," with the ground on top. Since then, I've noticed that they are this way in every hospital I've visited. I always wondered why, and recently I learned that it's a (marginal, IMO) safety feature. With the normal orientation, if a plug wasn't quite plugged all the way in, and a metal object fell on it, it could bridge the hot and neutral and cause a short, or worse, touch just the hot and create an electrocution hazard. Apparently it recently became code in Virginia for commercial construction that the outlets be mounted "upside-down," though it is still not mandated for residential construction. Fact is, I think they look awful upside-down; I can't decide if this is just conditioning because I've seen them the other way all my life, or if there is a real aesthetic imbalance going on.
