It seems that the Twitter post "red lunch time mount elizabeth hospital" does not relate to a maintenance report feedback for a public flat house. The term "red lunch time" does not suggest any specific issue or facility related to maintenance, and "mount elizabeth hospital" is a medical facility, not a public flat house. Therefore, the answer is that the post does not relate to a maintenance report feedback for a public flat house.
