It seems that the tweet "nasty cookie singapore" does not relate to a maintenance report feedback for a public flat house. It is possible that the user is simply expressing their displeasure with a particular cookie they purchased in Singapore, or it could be a completely unrelated topic. Without more context or information, it is difficult to determine the exact nature of the tweet.
