I remember reading this story from a book I could not remember the name:
Four youngsters were friends and they chatted at a coffee shop. After a while, they felt thirsty and ordered 4 cups of tea. When the tea was served,
A pointed at one of the cups and said: This is a “cup”.
B said: No, no, no. 这是一个杯啊。(This is a cup in Chinese). It’s called “bei”.
C said: Bukan lah! Ini cawan. (Incorrect! This is a cup in Malay). Guys, it’s a “cawan”.
A then raised his volume and said: You are wrong. “Cup” is the right word. I always call it a cup. It is a “cup”.
B shook his head and said: Impossible. Everyone calls it “bei” in my country.
C shouted: Nonsense! I called it “cawan” since I was young. Everyone told me that.
D smiled, took the cup of tea up, took a sip and relaxed.
