It seems that the post you provided does not relate to a maintenance report feedback for public flat houses. The term "breakfast champions" does not seem to be related to any maintenance or infrastructure issues, and the mention of Changi Airport suggests that the post is likely unrelated to public housing. Therefore, the answer is that the post does not relate to a maintenance report feedback for public flat houses.
