JOLIET, IL— According to eyewitness reports, two employees at a local Walgreens engaged in a heated argument Sunday in full view of customers, shattering the air of decorum traditionally associated with the drugstore chain. "Like most people, I've come to expect a certain level of courtesy and professionalism when I enter a Walgreens—the kind of effortless competence all retailers aspire to but few ever achieve," said shaken patron Gabe Lawrie, 28, who described two checkout clerks engaging in a loud dispute and not even acknowledging his presence until their exchange was interrupted when one took a personal phone call. "When you hear the name Walgreens, you think: an expert staff with a thorough knowledge of the store's products and—above all else—an unfailing respect for the dignity of the customer. I was looking around thinking, 'Is this a Walgreens? Am I in the wrong store?'" Lawrie then shook his head and crossed the street to CVS, where a white-gloved assistant manager greeted him with direct eye contact and a deep bow.
