Brunei $$ vs Singapore $$

We were queuing at Cold Storage behind this family of 3. The dad, handed $50 to the cashier,

Cashier gave back his change. They walked off, dad check change then dad walk back to counter.
(in trueblue Singlish)
Mr Dad : err cuse me.. this one ar Brunei dollar.. (showing a BR$10 note)
Cashier Aunty : can use one..
Mr Dad looking somewhat blur : can change or not?
Cashier Aunty : (still persistent) err can use one la..
Mr Dad : (also persistent but still polite) err err...

then my kaypoh hubby interrupted still in singlish ahhaha

Mr Hubby : Excuse me.. this one can be used.. if u don't want, can change with me or not??
Mr Dad : (gladly change)
Mr Hubby : (smiling smiling with his latest collection)

This remind me of my first working experience at 7 Eleven bout 20 years ago.

After a few days of stacking boxes, I was so excited that i was given the chance to do cashier.
Feeling all important and gloating all day.

At the end of the shift, Angelia aka Angie (see i can still remember her name) call me in.

She showed me a Brunei note which i remembered accepting (because the customer did ask me wether i accept it or not and i told him yes)

She asked... nope.. she railed at me, why i didn't check and accept "Ringgit Malaysia" etc etc la.

No matter how many times i tried explaining that it is "Brunei Dollar" and not ringgit she still insisted that i'm wrong.

Boy.. she must have really bad eyesight or have problem differentiating "Brunei" and "Malaysia" on the note.

Anyway, i didn't get another stab at cashier hahah but It's ok cos i quit few days later. hahahah

So back to Coldstorage incident. Next day, I asked some of my friends... and 1 or 2 don't know that Brunei dollar is accepted here.

And since i can't sleep tonight... let me share this which is taken from MAS

The Currency Interchangeability Agreement
The Currency Interchangeability Agreement with Brunei took effect from 12 June 1967. Under the agreement, each country undertakes to accept the currency issued by the other and to exchange them, at par and without charge, into their own currency. In other words, the two currencies are "customary tender" when circulating in the country in which they are not legal tender. Relevant extracts from the agreement are reproduced below:

"2(a)(i)
The Brunei Currency Board will accept from banks in Brunei, notes and coins issued by the Board of Commissioners of Currency, Singapore, and will exchange such notes and coins, at par and without charge, into notes and coins issued by the Brunei Currency Board;
(b)(i)
The Board of Commissioners of Currency, Singapore, will accept from banks in Singapore, notes and coins issued by the Brunei Currency Board, and will exchange such notes and coins, at par and without charge, into notes and coins issued by the Board of Commissioners of Currency, Singapore;
3(b)
The Board of Commissioners of Currency, Singapore, will inform all licensed banks in Singapore of the arrangements referred to in paragraph 2 above, and will request all banks to accept, at par and without charge, notes and coins issued by the Brunei Currency Board, and to exchange such notes and coins into notes and coins issued by the Board of Commissioners of Currency, Singapore."
