Jaspas Restaurant (已結業)

I was teased by a waiter when I was having lunch there today. I mispronounced the word soup and the Asian-looking waiter who looks like a Chinese imitated my articulation and shared the tease with a waitress. I was really embarrassed and offended. I'm a Hong Konger. Is the restaurant only serves those who speak perfect English? As long as I could communicate with the waiter, I think I shouldn't have been laughed. Although food matters much in a restaurant, decent service is also indispensable.
