Darden Restaurants, Inc. has agreed to pay another $4 million to settle another two class action lawsuits involving California employees of Red Lobster and Olive Garden restaurants. The suits accused the company of requiring servers and bartenders to make up for cash shortages at the end of their shifts. The settlements were disclosed in recent S.E.C. filings. A company spokesman said the settlements the allegations were "almost impossible to prove one way or the other," but that the defending the cases would be too costly.
