I'm not sure if that should be in the humour section. It isn't funny.

Change the end so that it is:

The German comes back to find the note gone.
the hotellier apologises and calls the Police
The Police investigate and cannot help.
The German goes home, cross and swears never to go back to Greece.

Then it is 100% as it is.
