Clean dishes should be free

"One yuan," I read the price tag on a dish package and said to my friend who was on a business trip to Beijing, "Isn't the service nice in the capital city? You can have alternative dishware if you want."

"Yes, but we don't need that. This restaurant looks pretty nice and its own dishes should be fine," said my friend, who works in Shanghai. You know the rational Shanghai style. Then I asked a waitress over.

"Shall we pay for that broccoli dish?" my friend asked, trying to remain elegant. "No, that's from our own supply, not from sanitized dish providers," the waitress answered.
