Every visit starts from zero. Where the vacuum lives, which room is off-limits, that the dining table is a soft finish and takes no spray at all: none of it survives into the next visit, because the next visit is a different person who was told none of it.
So the client re-explains, or stops re-explaining and quietly starts noticing that it is not as good as it was.
