A friend and I were standing in line at a fast-food restaurant, waiting to place our order. There was a big sign posted. "No bills larger than $20 will be accepted."
我和一個朋友在快餐店排隊訂餐，那里很醒目地寫著，不接受超過20美元的大鈔(請自備零錢)。

The woman in front of us, pointing to the sign, remarked, "Believe me, if I HAD a bill larger than $20, I wouldn't be eating here."
我們前邊的一個女士指著這個牌子對我們說：“上帝保佑，如果我身上有超過20美元的話，我一定不會在這兒吃飯!”
