Me - Sorry sir, I am African and I have realised that we didn't use the main entrance. Are you trying to say that we Blacks are idiots? (Thinking, "should I even add to him that this little room is called a black box?")
A - Ah, no, sorry, I was kidding - he said, with a yellow smile that made me sick.
Me - ... - just looking at him with my killer look. Aaaash!
