The Flames-Oilers rivalry is reaching a whole new level.

A Calgary restaurant owner is calling unsportsmanlike conduct on some Edmonton Oilers players he says skipped out on part of a huge New Year’s Eve bill, following the team’s 2-1 loss to the hometown Flames.

TSN.ca reports that Osteria De Medici owner Maurizio Terrigno says the players partied in a group that included 45 people, and the drinks were flowing to the tune of $8,200, and the total bill came to nearly $17,000.

The restaurant owner says the players demanded a discount when they got the bill, and eventually left $12,000 before leaving.

He’s decided to donate the the money he did get to an earthquake relief fund for people in L’Aquila, Italy.

Oilers spokesman Allan Watt told TSN.ca the restaurant was recommended by some Calgary friends of the players and they had a prearranged meal and menu.

“They received the bill which they felt was outrageous,” said Watt.

“They inquired about it and they were unhappy about it and were unhappy with some of the charges. The restaurant adjusted it by $7,000.”

Watt said the players paid the adjusted bill and added a $1,900 tip and left the restaurant.
