mattp,
Also of note is the relativity of $150 immediately after you have had the first two glasses of a really good wine. Many a second, unaffordable bottle has been ordered in this manner.
Also, it was Ovid way back in Rome, in Ars Amatoria (a "player's guide" written 2000 years ago), who wrote "beware of the low lights and wine" when trolling for the ladies. We know that today as the trask phenomenon, or coyote-ugly.
