Iraqi WMD isn't a lie, it was bad information. If you tell someone you think the restaurant looks like it doesn't have a long wait, only to walk inside and discover it does, does that mean you deliberately lied? No.
Brilliant analogy. And then, after realizing that there is a long wait, you figure, "Let's stick around and see what that salad bar is all about." Of course, half way through the wait, another guest might announce that there actually isn't the long wait that everyone thought there was. He would subsequently be voted out of the area by 17 points, of course, but he'll be back. Don't you worry.
Not only that, but you'd be calling up all your friends and telling them that there is no wait at all. And as far as I can tell, the only motivation for staying in line (despite the fact that your kids are hungry and want to eat
now) is that your father had dinner at this restaurant twelve years ago and didn't finish his meal.
