对不起，本店不找零钱

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."

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."

我和一个朋友在快餐店排队订餐，那里很醒目地写着，不接受超过20美元的大钞（请自备零钱）。
我们前边的一个女士指着这个牌子对我们说：“上帝保佑，如果我身上有超过20美元的话，我一定不会在这儿吃饭！”
