PORTLAND, Maine (AP) — Two employees of a Portland hotel have filed a lawsuit alleging management did not give them all the tips to which they were entitled, according to the Portland Press Herald.

Jeffrey Stone and Kimberly Williams on Monday filed a “tip skimming” class action suit in Cumberland County Superior Court against the owners and operators of the Eastland Park Hotel.

The complaint says the hotel adds a gratuity of 18 to 20 percent to food and beverage bills, including banquets.

The Portland Press Herald reports that the complaint alleges the hotel keeps a portion of gratuities for itself or distributes a portion to managers or other employees who do not serve food or beverages.

Williams has worked as a banquet server at the Eastland since 2004. Stone has worked at the hotel since last year.

Ownership had no comment.
