Agreed about standardization; knowing what to expect is useful in communication generally. My dad (former pilot) is fond of pointing out that this is how pilots and ATC people understand each other over crackly radios. There’s only a small set of possible things they could be saying, and they know what to expect, so they only have to listen for whether the crackly voice matches what they’re expecting.
even if that means taking twice as long to get to the point
I still find the time argument odd. The difference doesn’t seem like that much to me, and the couple of seconds seem trivial weighed against the social currency you gain by taking them.
Hmm—my goal is to inform the other person of the error. This does not require them to respond.
