Last weekend at the Jewel on Southport I stood next to a couple of twentysomething guys who were looking over spaghetti sauces. Suddenly a 30-ish man turned into our aisle and breezily pushed his cart behind us. "Excuse me, ladies," he deadpanned and kept going. The two guys looked at each other. "Fuck him," said one under his breath. "What attitude for a Jewel."
