Normally the pricing around the place is Caucasian v's Asian.

Well one place seems to be having an Asian issue of Korean v's Thai & Chinese.

I have seem previously where Japanese is held for a different price as well.

So obviously there is a totem pole arrangement for different nationalities with Chinese at the bottom it seems.

So it seems obvious that Caucasian is at the top and asian underneath,, but maybe this should be broken down further with the Caucasian broken into Australian, USA, Canada, NZ, English, Western European, etc., etc
And the Asian into their respective areas.

Now, please do not think me racist, but why are these divisions necessary and being pushed by the shops ??

Yes, we all know is money, but really in this day and age should this political incorrectness exist.
