It seems that the post does not relate to a maintenance report feedback to public flat house. The term "lunch" does not mention any facilities, inconveniences, block numbers, or streets related to public housing, and it does not appear to be a request for maintenance. Therefore, the answer is that the post does not relate to a maintenance report feedback to public flat house.
