Sinkies are really low ses coolies, no match for the Tiongs billionaire washing machine and CECAs CEOs. Can only wash toilets, drive grab, become hawkers.
I have worked in several banks.
My those bank colleagues always use the company name together with er to make it sounds more legit.
Eg work in citibank, they call themselves citibanker.
But I told them pls exclude me from this term.
