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 "lincoln grill singapore" does not appear to be related to any specific topic or issue related to public housing in Singapore. Therefore, the answer is "False" for the question "Does the post relate to a maintenance report feedback to public flat house (e.g., a broken facility, an inconvenience, block number or street, requst fixing, etc.)?"
