if all government office allow you to deal with foreign language, then people dont find necessary need to learn it. besar suara sikit pon terasa, hati tisu betul. alot of time gomen officer being rude also because their customer are rude in first place, cuba cakap baik2 in reduced tone, you may get treated differently.

this situation is not exclusive to malaysia.
