Great story, and also gave me a flash of insight: when considering people to work with, "Would I plan a bank heist with this person?" isn't a half bad question to ask. It implies complete trust both in the person and their ability to perform.
(Or maybe I'm just goofy...when I can't put my finger on what's causing me to hesitate about a person or situation, off-the-wall questions/scenarios usually help me figure out what's really bothering me.)
