It seems that the Twitter post does not relate to a maintenance report feedback for a public flat house. The post mentions "halls" and "Singapore food waste free," but there is no mention of any specific issue or problem related to a public flat house. Therefore, the post does not fit into any of the categories mentioned in the question.
