SMU School of Social Sciences graduate Jack Sai was the first to join the family business full-time in 2011. Coffee Break is a drinks stall at Amoy Street Food Centre that is run by third-generation "hawkerpreneurs" Jack and his sisters, twins Faye and Anna.  For starters, they are proffering an improved blend of coffee beans that goes into their bold variety of flavoured coffee drinks, and are coming up with quirky spreads for their toast. Aside from the traditional kopi variations, Coffee Break also serves lattes and flavoured coffee drinks, made using “sock-brewed espresso”. Moving forward, they are preparing to open a standalone outlet at a new office building, located next to Kent Ridge MRT Station, by end-September, which Jack said the sisters will run, while he will continue to man the Amoy Street stall. There are also plans to open a third outlet at Raffles Place by the end of the year or by January next year, which is why they are looking to hire, he added.
