The Man in Sunglasses
You scurry after the sunglasses guy, trying to look casual and definitely not like a lost intern. Then — SPLAT — your sneaker lands squarely on his trailing shoelace. He goes down like a sack of potatoes wearing a trench coat.
A silver USB drive pops out of his pocket and skids across the marble floor. You pick it up. 'Sir, you dropped this!' you chirp helpfully. He snatches it back, hisses something in what might be Latvian, then drops it again as he sprints away. Weird guy.
