Just change the word Chinese for British or English and the case is the same.
How many western expats speak Thai (no need to sound offended if you do), and how many go for an English breakfast still?
Moreover, Thais sometimes don't know which of their dishes are originally Chinese, or Chinese influenced, like Ba Mii (บะหมี่) clear egg noodle soup, Khanom Jiin (ขนมจีน) fermented rice noodles with curry sauce accompaniments, Guay Chap (ก๋วยจั๊บ) a pork flavoured soup and Guay Tiaw (ก๋วยเตี๋ยว), Jok (โจ๊ก), a rice porridge called congee sometimes, Salapao (ซาลาเปา), steamed buns and Khao Kha Moo (ข้าวขาหมู), fragrant stewed pork with rice.
