if you park your car in th wrong place ,a traffic policeman will soon find it .you will be very lucky if he lets you go without a ticket .however,this does not always happen,traffic police are sometimes very polite.during a holiday in sweden,i found this note on my car ,'sir,we welcom you to our city,this is a no parking,area,you wil enjoy your stay here if you pay attention to our street sings,this note is only  a reminder .if you receive a request like this ,you cannot fail to obey it !
