>useful if it's generic fluff like char speaking with some random civilian on the way to the supermarket doing a mundane task to establish how she talks.
specifications like that are actively poisonous to your outputs unless you're exclusively creating a scenario in which "your character is speaking to a random civilian on the way to the supermarket" - the LLM will have to read this exact scenario every time and will inevitably get a wire crossed because of it

in your example, it would be better to simply state the way your character talks within your actual character profile 'stat sheet', eg. specific dialect habits and accent.
using the example dialogue means that's the way the world speaks (every character affected), you don't want to use it for individual cases (unless it's literally just you and character in a room forever and you never want to advance beyond that?)
