McDonald's restaurants serve billions of hamburgers every year, but there's one restaurant where the workers are the ones being served by a very special woman. Andrea De La Rosa is an assistant manager at a McDonald's restaurant in Lowell, Massachusetts, US, who has offered countless kids working at her store a heaping helping of love and guidance. "You never stop being a mother just because they're not your kids," De La Rosa told CBS News. Managing young people on their first job is about much more than barking orders, according to De La Rosa. It's about listening, helping with homework, college applications, and really anything for the kids who work in the restaurant. Employees say De La Rosa will pick up her phone no matter what time of day and gives some the mother figure they are missing. "It's a little bit of kindness. A little bit of love that means the world to somebody," she said.
