Yesterday in the standing room line for Un Ballo in Maschera, two men behind me were yelling at each other. "Shut up!" said one, and "No, you shut up!" said the other. At first I assumed they must be friends simply having a bit of fun, but it became clear this altercation was in earnest. Strangely enough, there were only 5 people in line. A lady behind me asked if I had been waiting ahead of her, and I confirmed that I was second. She asserted that she was before the yelling men, and they let her be third. It was all especially bizarre since one of the men did not materialize at the appointed time for when they allow us in to take our spots.
