It seems that the Twitter post you provided does not mention anything related to maintenance report feedback for a public flat house in Singapore. The term "morphine coffee" is likely a reference to a coffee shop or cafe, and not related to any maintenance issue. Therefore, the answer is that the post does not relate to a maintenance report feedback for a public flat house.
