<P> At some holiday meals, such as Christmas in Protestant countries and Thanksgiving in the United States, it is customary for the host to prepare much more food than can be eaten, specifically in order to send leftovers home with the guests . Cold turkey is archetypal in the United States as a Thanksgiving leftover, with turkey meat often reappearing in sandwiches, soups, and casseroles for several days after the feast . </P> <P> During the late 19th and early 20th centuries, Chinese cuisine gained a foothold in the USA with the opening of several chop suey restaurants . There is no set history of how American diners became enamored of "chop suey"--which means "assorted pieces" or "miscellaneous leftovers"--although it is unlikely that actual leftovers were served at any chop suey restaurants . </P> <P> Leftovers from a restaurant meal may either be left behind to be discarded by the restaurant or taken away by the diner for later consumption . In order to take the food away, the diner may make a request for it to be packaged . The container used for such leftovers is commonly called a doggy bag or doggie bag . It is speculated that this derives from the euphemistic pretense that the food will be given to the diner's pet, rather than eaten by a person . However it may also be a corruption of the East Anglian term docky, meaning lunch . The term doggy bag was popularized in the 1970s etiquette columns of many newspapers . Doggy bags are most common in restaurants that offer a take - out food service as well as sit - down meals, and their prevalence as an accepted social custom varies widely by location . In some countries, especially in Europe, some people would frown upon a diner asking for a doggy bag . </P> <Ul> <Li> <P> Restaurant patron showing his leftovers to be put in a doggy bag </P> </Li> </Ul>
