WESTWOOD — Just a few minutes after ordering Mozzarella on his gourmet sandwich from The Study, first-year Hill resident Ben Larson realized his blunder. “The mozzarella will disrupt the harmony of the tomato pesto and toasted rye. What was I thinking?” said Ben, as he went to fill his reusable bottle with Viennese coffee, “I had to literally stand there and watch them make the wrong sandwich,” he recalled. “It’s the worst thing that’s happened to me since I found out my dorm doesn’t come with glow-in-the-dark ceiling stars.” Meanwhile a similar occurrence happened in Westwood that night when Julie Chen, an off campus resident, lay in deep regret for choosing to buy a toothbrush instead of toilet paper.
