I read Kim as a little bit on edge, so I just called somebody at a different branch. On my second call with Chris, the survey trick played like a charm. The tactic here is to slip the important questions in among inconsequential ones that are used to create a sense of believability. Before I dropped the question about the Merchant ID number with CreditChex, I ran a little last-minute test by asking her a personal question about how long she'd been with the bank.
