上饭店吃饭点菜，先注意价格再决定吃怎样的菜；I think everyone is doing it in American. In china, people don't do that, they spend more for the "diginity".
多要几份沾汤的免费饼干，因为 my kids like it.

But, I don't ask them to ware Chinese cloth because it doesn't fit in. It make them embarance in the public. I don't ask them share drink if it can be refill that means the cup should only for one person.
