USD Two Dollars?!?

Have you ever heard of 2 dollars being called U S D (sebut satu2) two dollars, or even R P H 1000 Rupiah?? Dun think this happens anywhere else in the world, except Malaysia.. Ever since they announced the RM sign for the ringgit, there has been various versions of how we use this... The most common are:

1. Saying R M (satu satu) followed by the amount, such as during the recent Anugerah Seri Angkasa, where PM was there, and whenever they announced the prize money that came with the award, it'll be 'wang tunai sebanyak R M 5,000' wtf?!?

2. The other more irritating one, is saying R M followed by the amount, and then add ringgit at the back, a clear example is if u ride the lrt and they have these annoucements for the new Rapid KL bus, it'll say 'bla bla bla dengan bayaran hanya R M dua ringgit', again wtf?!?

Don't they know that u shud just say dua ringgit ajelah, yang R M tu is a currency symbol. I guess its typical of us Malaysians, not paying enough on details and buat kerja asal boleh aje... Malaysia Boleh!
