Jeff Bezos kept a public email address for Amazon customers. “I still have an email address that customers can write to,” he said in 2018. When a complaint caught his attention, he forwarded it to one of his executives with one character added: a question mark.
Bezos explained: “That question mark is just a shorthand for, ‘Can you look into this? Why is this happening? What’s going on?'” A former manager described the effect: “By the morning, I better have a damn good resolution to whatever this is.”
