还有一次，当我把拾到的饭卡还给食堂时，工作人员竟然让我把里面的钱花了，不必费心去寻找失主。

Then another time, when I returned a lost dining card to the canteen, the staff asked me to use up the cash on it rather than bothering to find the owner.

如果你住校的话，你在任何一个餐厅吃饭都可以用饭卡，所有的食堂提供的食品也都不一样。

If you live in University housing you can use credits/meals at any dorm on campus and they are all very different.

在食堂门口设有查询机，就餐人员可以自行查询饭卡的消费情况、餐补发放情况、饭卡充值情况。

There exists one inquiry machine at the entrance of canteen. We can query consumption information, meal allowance and etc.
