Got on the elevator with the two doglets. A skinny old guy (maybe mid-fifties) was already there, puffing away at a cigarette. He was quite friendly.
"What country are you from," he asked.
I said, as I always do, "China."
He laughed. "No, really!"
I responded: "Of course I'm Chinese. I can read Chinese, whereas you obviously can't." He laughed again.
Then I pointed to the very prominent sign which reads "Please do not smoke here" in perfectly good Chinese. I scolded him for being a Japanese in China, and I read each character out loud.
(Calling a Chinese person Japanese is like calling Donald Trump a Mexican. YUUge insult!)
He laughed a big belly-laugh, and said "You're Russian?"
I said yes, I'm Russian. Then the elevator door finally opened and let some fresh air in.
