Unfortunately, yes. I do have my own word for such people: wrong. As in, they probably never experienced a collaborative workload that's high enough to teach them the value of succinct and precise communication. Or, as my wife would say, you can tell who had an actual high-pressure office job by their communication style.

So do I. So do most people, or at least they think so. The problem is, people don't read letter by letter, or word by word. They read by pattern-matching word shapes and sentence shapes - which leads to all kinds of misreadings. It's not an issue in prose, or in high-stakes situations when people are careful. It is an issue in a typical e-commerce conversation, though.
I'm considered a careful reader by people in my circles, and often get to proof-read other peoples' messages. In that role, I've seen first-hand how people can misread "three days" as "three weeks", or "X is not available" as "X is available", etc., because the information was puffed up into a whole paragraph, and the person read it too fast. Being "curt" would've saved both the buyer and the seller from having a bad day.
