“NORTHAMPTON, MA—With her remarkable ability to determine exactly how others should be allocating their limited resources for food, local woman Carol Gaither is considered to be one of the foremost authorities on what poor people should and should not have in their grocery carts, sources said Thursday.
As verified by multiple eyewitness reports from supermarkets across the Northampton area, the real estate agent and mother of three is capable of scanning the contents of any low-income person’s basket and rapidly identifying those items which people like that don’t need to be buying, based on the products’ nutrition and cost. Additionally, Gaither, 48, is widely regarded as a leading expert in determining which groceries they would purchase instead if they had any common sense or restraint.”
