At the food counters in a store, a customer was complaining to the shop assistant.

“I don’t want this box of food. Please give me my money back.”

“Sorry, Madam. You know, food cannot be returned after it is sold,” the assistant explained.

“But I can’t pay for this fake food,” the customer insisted.

“How can you prove that this is fake food?” the assistant asked angrily.

“Look at the label on the box. The Date of Production: June 31,2003. How

can you prove that there are thirty-one days in June?” the customer reported.

伪劣商品

在一家商品的食品柜台，一位顾客正在向售货员申诉。

“我不想要这和点心了。请给我退款吧。”

“对不起，食品售出后恕不退回。”

“但我可不能花钱买件伪劣商品呀。”

“你怎么证明它是伪劣商品呢？”售货员生气地问。

“瞧这盒上的标签。生产日期是2003年6月31日。6月份哪会有31天呢？”顾客反驳说。
