The bottle shape should have tipped off the server that the wine was a Burgundy and not a Bordeaux. So I question how much of an accident this was.
My wife and I once went to a restaurant that mixed up the wine order but put the expensive one on the bill. I refused to pay and after some argument paid the price of the cheaper wine instead.
I'm sure he was out considerably less than that unless he sells his liquor at cost.
My FIL was was a Restranteur in San Francisco. One day he showed up with a bottle of Domaine Perignon which normally was $ 125-150 a bottle at the time. He had KFC with him at the time. We had lunch with Domaine Perignon and KFC. Nothing special regarding the taste. It was good but far from over $100 a bottle. This was in the 80’s.
