This is just a staged ploy by the Opposition to aggravate any PAP minister. It has been going around 10 PAP constituencies. Their hope is to make PAP ministers lose temper and thus look bad on social media to reduce their chances in the elections.
Just a reminder, because it seems to occur to most Samsters only that the PAP might have staged it, not that the Oppo might also have staged it. Anyway, it's this EDMWer's opinion, not mine.
