Sorry everyone.
I think I did not capture the main question I would like to ask. I did not express myself very well.
I will try to ask again.
The other day I went to a Chinese restaurant for dinner.
The price is in ¥ (currency of China) only on their iPad menu, but the price on the menu is the price I should be paying in $ (AUD).
The bill was around 95¥, but obviously what they want to charge is 95$.
So can I pay 95¥ or I still have to pay 95$ for the bill?
You pay in the currency listed on the app.
