Outdated Food Items

Recently there was a story on television about people buying outdated food items at several types of stores. They then returned them to let the managers know that they were outdated. The next day this reporter returned back to some of these stores and the items were placed back on the shelf. Of course, none of the managers wanted to be shown or speak. I usually check dates but on canned goods or packaged items I'm not always real good about that so this will hopefully make me more aware of the dates placed on food items.
