对不起，本店不找零钱

A friend and I were standing1 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, remarked2, Believe me, if I HAD a bill larger than $20, I wouldn't be eating here.

中文翻译
我和一个朋友在速食餐厅排队订餐，那里非常显眼地写着，不同意超越20USD的大钞（请自备零钱）。
大家前边的一个女性指着这个牌子对大家说：上帝保佑，假如我身上有超越20USD的话，我肯定不会在这儿吃饭！
