It seems that the Twitter post you provided does not relate to a maintenance report feedback for a public flat house in Singapore. The term "dropoff" is not a term commonly used in the context of maintenance reports, and "save mart" is not a term associated with public housing in Singapore. Therefore, the post does not meet the criteria for a maintenance report feedback.
