The Receipt's Purpose
(Originally in English)

At the traffic fine office, the police handed a motorist a
receipt for his traffic fine. The motorist must have been
fined for speeding. He grumbled, "What am I supposed
to do with this?" The clerk advised him, "Keep it. When
you get four of these, you get a bicycle!" By that time,
he wouldn't be allowed to drive a car!

收据的用途

在交通裁决所的办公室里，一位办事员开了一张收据给一名刚缴完
罚款的汽车驾驶人，这个人可能是因为超速而受罚，他发牢骚地说：
「我要怎么处理这张收据？」办事员建议道：「保留起来，等拿到
四张收据时，你就会有一部脚踏车了！」因为那时候他就不能再开车了!
