As many know, APAC dining discounts for elites are still alive and well at many properties, even if not well-advertised.
I should share something I discovered at my current hotel in China. The in-room dining menu QR opens a website to order food. Fellow non-Chinese travellers may be tempted to peruse the menu in English. However, toggling the menu to Chinese reveals membership-based discounts applicable against the whole menu. Basic members get 10% off. Titanium seems to be about 18% off. The discount is only offerred when ordering from the menu in Chinese and is wholly absent when ordering from the English version online or by phone. The price differences are reflected on the receipt you are asked to sign.
Just an FYI as you wouldn't even know about the discounts unless you specifically pulled up the online Chinese version of the menu (scanning the QR outside of Wechat defaults to English, scanning in Wechat or toggling from English to Chinese reveals the discounted pricing). I'm sure it's just a reflection of the small number of English-speaking guests leading to someone in IT forgetting to implement on the English side, rather than some intentional price discrimination for international non-Chinese travellers
(I will be asking for some price matching at check-out for the orders placed on the English side before I discovered this, which I'm sure they'll oblige).
