Why? Because I was asking them for very sensitive information, and they weren’t going to give that out to just anybody. So my pretext was, "I’m setting up a database of people on call to handle mission-critical problems." One by one, I’d first ask a series of innocuous questions—"May I get your name, please?" "You work out of which Dispatch Center?" "Who’s your manager?" Once they’d established a pattern of answering my questions, I’d ask for what I really wanted: "What’s your UUID? And your tech code?"
