Then there was Chris, who came almost every night with the quiet of someone who thought himself invisible. He liked his nachos “strangely specific”: extra black beans, a drizzle of lime, a sprinkle of chives stolen—he’d joke—from the fancy places. He paid in exact change and left his phone face-down on the table until his food arrived, as if guarding something from distraction. Nikki watched him, not out of curiosity but because people were her work, and noticing subtleties was part of the job.
