Hey, it's the weekend. You're out with friends. Lets go mad and order a bottle of wine ... but be careful. Or else you'll be spending the equivalent of your monthly mortgage payment on a bottle of plonk!

Joe Lentini was dining with friends in a steak house in New Jersey in the US. He had a side order of WTF when the $37.50 bottle of wine he thought he ordered turned out to be worth an eye-watering $3750.

“I asked the waitress if she could recommend something decent because I don’t have experience with wine,” Mr Lentini told NJ.com.

“She pointed to a bottle on the menu. I didn’t have my glasses. I asked how much and she said, ‘Thirty-seven fifty.’”

Here's where it gets tricky. It turns out that bottle of wine, a 2011 bottle of Screaming Eagle, Oakville, costs $3750.

When the bill came, “we all had a heart attack,” one of Mr Lentini’s dining companions, Don Chin said.

They tried to negotiate the bill with the waitress and restaurant management but were told the best price the restaurant could offer was $2200. Mr Lentini and his two dining companions split the bill.

Mr Lentini said the wine wasn’t even that good. “It wasn’t great. It wasn’t terrible. It was fine.”
