Young Chang Kee (“YCK”) ordered three ovens from Chef Supplies to replace his old ovens at his famous shop at Katong selling curry chicken pies. YCK informed Chef Supplies that the ovens were part of his business expansion plan. The ovens were to be installed by 1 June but Chef Supplies only completed the installation on 30 June. During the 30 days of delay, YCK lost $10,000 in profits from walk-in customers and online orders. YCK also lost $5,000 in potential profits because he had to turn away a lucrative delivery order from a foreign workers’ dormitory. a) On what ground can YCK sue Chef Supplies?

(b) Explain the difference between the $10,000 loss in profits and the $5,000 loss in potential profits.
