It seems that the tweet you provided does not relate to a maintenance report feedback for a public flat house. The tweet simply mentions "sushiro singapore" without any context or information that would suggest otherwise. Therefore, the answer is that the post does not relate to a maintenance report feedback for a public flat house.
