The Steak n Shake Co. has agreed to pay $180,000 to settle a sexual harassment lawsuit filed by a woman who said she was groped by a fellow employee and that a restaurant manager and assistant manager refused to help her.

The lawsuit alleged that in the summer of 2002, Amanda Nichols, then 17, was subjected to unwanted sexual advances by another worker at a suburban St. Louis restaurant, the U.S. Equal Employment Opportunity Commission said Thursday.
