The ticket had been a perfect match for the wrong day, bringing the celebrations to an abrupt halt.
One dishwasher even thrown his apron off, declaring "I'm outta here! I quit!".
"It was like getting punched in the stomach," bartender Charles Poveromo told The New York Post.
"There was just so much joy, and I can't put into words the feelings of euphoria that we all felt."
Poveromo's wife sensibly suggested he double check the numbers and the party came crashing down.
"It was like a balloon deflating," he said.
The dishwasher who had just quit reportedly picked his apron up and said "back to work."
