Reminds me of the Ethshar series. I don’t remember what book it happens in, but in one of them, it’s a bit of worldbuilding that Divination wizards typically do a quick divination in the morning to see what clients they’ll get that day, then also do a divination to see what they’ll want to ask. That way, when the client comes into their shop, the wizard already knows who they are, what their question is, and the answer to the question, proving their abilities.
