International English

In a Tokyo Hotel: "It is forbidden to steal hotel towels please.  If you are not a person to do such thing is please not to read this notis." (Since you've read this note, you should go ahead)

In a Bucharest Hotel: "The lift is being fixed for the next days.  During that time, we regret you will be unbearable."

In a Paris Hotel: "Please leave your value at the front desk."  (sounds very appropriate for Paris).

In Athens:

"1) Visitors are expected to complain at the office 9am-12pm 

 2) The flattening of underwear with pleasure is the job of the chambermaid." (这应该是事后吧，大裤叉子都皱了）
