Fine?

Some English words have several meanings. This thing sometime causes misunderstandings. I got an interesting topic about it.
A Japanese man was trying to park his car in Los Angeles. At last he saw empty space. There was a notice saying"Fine for Parking!" He parked his car and left. However, when he came back there, he found an angry police officer. The officer shouted, "Can't he read the notice?" He answered, "Well, yes, I can read it, but it says fine. That means it is a good place for parking, doesn't it?" The police officer seemed to have a good sense of humor. After laughing a bit, he said, "In this case , fine means money that you have to pay as a penalty if you do something wrong. So you are not allowed to park here." Luckily, the police officer let him go with just a warning.
I didn't know that there was the meaning of the penalty in "fine". I looked up fine in a dictionary after I had read this topic. I thought it to be interesting and the etymology is incomprehensible.(188words)
