In a social and public setting, and a figure like her, in any countries, by the least standard lah, would have asked for the person’s name and just reciprocate accordingly, whether it is a handshake or just saying hi hello back to the person. It doesn’t matter what job the person is holding. Just basic courtesy when interacting with the public with her MP job.
But she did not even possess the basic standard and courtesy to manage social interactions.

Goes to show her upbringing and lack of social skills and all the money wasted to pay for her salary all these years and money invested to train her for the MP job and whatever ranks and titles she has been holding. This kind of thing also must teach meh.
SkillsFuture got basic courtesy course bo? Maybe she can consider taking up and see how.
Also, if today, common people like me and you, who are not public figures, if people popped out and come and offer me handshake, I can choose not to reciprocate also because we are all strangers. But she isn’t.
