It seems that the tweet "mmmmm causeway 0 singapore" does not contain any information related to a maintenance report feedback for a public flat house. The term "causeway" is likely a location or a road name, and "0 singapore" may be a reference to the country or city where the location is located. However, there is no mention of any maintenance issue or feedback related to a public flat house. Therefore, the answer is that the post does not relate to a maintenance report feedback for a public flat house.
