At the time of Cullens death in 1936, there were seventeen King Kullen stores in operation. Although Saunders had brought the world self-service, uniform stores, and nationwide marketing, Cullen built on this idea by adding separate food departments, selling large volumes of food at discount prices and adding a parking lot. Other established American grocery chains in the 1930s, such as Kroger and Safeway Inc. at first resisted Cullens idea, but eventually were forced to build their own supermarkets as the economy sank into the Great Depression, while consumers were becoming price-sensitive at a level never experienced before. Kroger took the idea one step further and pioneered the first supermarket surrounded on all four sides by a parking lot.As larger chain supermarkets began to dominate the market in the US, able to supply consumers with the desired lower prices as opposed to the smaller "mom and pop" stands with considerably more overhead costs, the backlash of this infrastructure alteration was seen through numerous anti-chain campaigns. The idea of "monopsony", proposed by Cambridge economist Joan Robinson in 1933, that a single buyer could out-power the market of multiple sellers, became a strong anti-chain rhetorical device. With public backlash came political pressure to even the playing field for smaller vendors lacking the luxury of economies of scale.
These aisle ends are used to lure customers into making a snap purchase and to also entice them to shop down the aisle. The most obvious place supermarket layout influences consumers are at the checkout. Small displays of chocolates, magazines, and drinks are located at each checkout to tempt shoppers while they wait to be served. Criticisms
The large scale of supermarkets, while often improving cost and efficiency for customers, can place significant economic pressure on suppliers and smaller shopkeepers. Supermarkets often generate considerable food waste, although modern technologies such as biomethanation units may be able to process the waste into an economical source of energy. Also, purchases tracking may help as supermarkets then become better able to size their stock (of perishable goods), reducing food spoilage. See also
