The stores were a financial success and Saunders began to offer franchises. The Great Atlantic & Pacific Tea Company, which was established in 1859, was another successful early grocery store chain in Canada and the United States, and became common in North American cities in the 1920s. Early self-service grocery stores did not sell fresh meats or produce. Combination stores that sold perishable items were developed in the 1920s. The general trend since then has been to stock shelves at night so that customers, the following day, can obtain their own goods and bring them to the front of the store to pay for them. Although there is a higher risk of shoplifting, the costs of appropriate security measures ideally will be outweighed by reduced labor costs.Historically, there has been debate about the origin of the supermarket, with King Kullen and Ralphs of California having strong claims. Other contenders included Weingartens and Henke & Pillot. To end the debate, the Food Marketing Institute in conjunction with the Smithsonian Institution and with funding from H.J. Heinz, researched the issue. They defined the attributes of a supermarket as "self-service, separate product departments, discount pricing, marketing and volume selling".They determined that the first true supermarket in the United States was opened by a former Kroger employee, Michael J. Cullen, on 4 August 1930, inside a 6,000-square-foot (560 m2) former garage in Jamaica, Queens in New York City. The store, King Kullen, operated under the slogan "Pile it high. Sell it low."
Zingo is a Swedish soft drink, with a carbonated orange flavor. Zingo was introduced during the 1950s as Ingo-dricka ("Ingo drink"), named after the boxer Ingemar "Ingo" Johansson. After Ingo lost the world championship in heavy weight boxing, the drink was renamed Zingo in 1962. Originally Zingo was produced in Norrköping, Sweden by Pripps. Pripps was bought by Carlsberg in 2000 and they continue to manufacture Zingo. Sources
