过了保质期

Excuse me, sir. Is there anything I can do for you?
请问，先生，我能帮您什么忙吗？
Yes. I bought the can two days ago, but today I found that is beyond the guarantee period.
是的，我在两天前买了这个罐头，可是今天我发现罐头居然已经过了保质期。

Let me see. I am sorry, sir. We will change another one for you. Please wait a moment.
让我看看，很抱歉，先生，我们会给您换一罐。请稍等。
