It means that a large part of my job is just copying and pasting things that have already been sent to clients because they straight up do not read everything they're sent even if it's just three or four sentences in a paragraph. This has gotten worse since Covid. Loads of these people are business owners, too. I can't imagine working for them, it must be a fucking nightmare.
edit: It also means a lot of clients balk at text communication entirely insisting that it's easier to explain something over the phone. Inevitably, the thing they absolutely needed to monopolize someone's time for can be expressed in a single fucking simple sentence.
