Really? Really?! Really?!?

The other day a friend of mine and I were having dinner at a simple (and empty) restaurant in Virginia Beach.  They had two glasses of Sauvignon Blanc on the menu - they were both from the same county in Australia and both 2007 vintage.  I asked the server what the difference was between the two wines.  He asked me: "Is there a price difference?"  I said, yes, and noted that one was $1.50 more per glass than the other.  He said: "the more expensive one is better."
