Many in Singapore are aware that, for the past 40 years, as a result of the Currency Interchangeability Agreement, Brunei dollar notes are legal tender in Singapore.

On Sunday, I was at the Ngee Ann City outlet of Mos Burger and was told by the duty manager that the shop would not accept my friend's $5 Brunei note, as it was 'company policy'. This was despite my pointing out that it was legal tender.

I have two questions for the authorities. Are companies allowed to have such a policy, which is clearly against the spirit of the agreement? If the answer is 'no', how can consumers report such companies?
