It seems that the Twitter post you provided does not relate to a maintenance report feedback for a public flat house. The term "mcdonald singapore" does not provide any context or information that would suggest otherwise. Therefore, the answer is "no" for the question "Does the post relate to a maintenance report feedback to public flat house?"
