Two popular Southwest Michigan restaurants and their owner could end up paying $36,000 in back wages and fines to employees who a federal agency claims were short-changed in pay.

The U.S. Department of Labor filed a lawsuit on Monday in U.S. Sixth District Court against Clementine’s Saloon in South Haven, Clementine’s Too in St. Joseph and their owner Al Ruppert, according to online court documents. A news report on WOOD-TV of Grand Rapids said that employees brought forth the complaint to the Labor Department. But a spokesperson for Clementine’s said the restaurant wasn’t sure if that was the case or not.
