After finding a bug in my coffee and complained to manager. She spoke to me in Cantonese since she informed me she didn’t understand mandarin or English. But told me to f*ck myself which I believe is English. Only understood Cantonese, what kind of service is that, I understand this is Hong Kong but why would you say that to a customer who just found a bug in their coffee. Also should she speak Japanese since it is a Japanese restaurant.
