This restaurant is small and the menu is printed on the wall only in Chinese. I am a Chinese American here on holiday when a white man in his 20s comes in. He starts looking at the menu.
Waitress: No English.
Customer: (in Mandarin) No problem, I can read that and I speak Mandarin.
Waitress: Oh, really? You’re good.
Customer: Yes, I’m very fluent.
They speak in Mandarin for a while and chat while he eats. Later they speak in Taiwanese, which I didn’t understand but the waitress later said he’s also very fluent.. The guy then tries Cantonese but the waitress doesn’t speak it. I do, a bit. And his Cantonese is way better than mine. He then tries Shanghainese, which none of us understood but I assume he’s fluent as well.
The waitress was so impressed he got his meal free.
