“Working as a cashier turned me into an amateur sociologist. A frenetic stress animated so many of our customers. One of our neighbors would walk in and yell at me for the smallest of transgressions—not smiling at her, or bagging the groceries too heavy one day or too light the next. Some came into the store in a hurry, pacing between aisles, looking frantically for a particular item. But others waded through the aisles deliberately, carefully marking each item off of their list. Some folks purchased a lot of canned and frozen food, while others consistently arrived at the checkout counter with carts piled high with fresh produce. The more harried a customer, the more they purchased precooked or frozen food, the more likely they were to be poor. And I knew they were poor because of the clothes they wore or because they purchased their food with food stamps.” – J. D. Vance, Hillbilly Elegy
