Russell Blackburn doesn't think so. Back in January, the 59-year-old Blackburn was checking out at an Aurora Sam's Club. He paid for his dog food, cheese, milk and other items and then stood at the end of a long line of people waiting for yet another Sam's employee to check his receipt against the groceries in his cart. A diabetic, Blackburn realized that his blood sugar level was dropping; he was shaking and his vision was wonky. He says he knew that if he didn't get to the candy stashed in his car, he'd probably collapse. "Fuck it," he said, and he steered his cart toward the front of the line.
