When censuses and surveys today ask people how often they “dine out,” I don’t think people know what is being asked. While the intent may be to determine how often and where people eat away from home, I think the “dining out” question suggests to many people a white tablecloth “dining” experience. Many Americans, I believe, seldom go to “white tablecloth” restaurants, yet I find it hard, no, impossible to believe, that if you include fast food and all the kinds of eating experiences other than home, even if you exclude food brought from home, that no-one but an invalid does not participate in “dining out” experiences. Statistics should always be suspect, but fallible humans write the surveys. See this article for some good example of what I mean: http://blogs.seattleweekly.com/voracious/2011/10/majority_of_americans_havent_d.php
