That elite parent wants to have her right. A child that has a $60 haircut, and flaunted as a $60 haircut, cannot but has come from an elite family. The haircut is therefore not the key issue. The key issue is the elitist behaviour of not abiding to rules that all others are subjected to i.e. he wanted to be given the concession of a waiver and then feebly trying to bluff his way that he forgot because of his medical condition.
If all elites are given special treatment, I don't know what will become of Singapore. So HSK is right in his reprimand. I don't care which party he is affiliated to or whether it was because of his civil service experience but he acted correctly.
