Poznan Approach (that is in Poland, Europe). The conversation is carried with heavy accent as pilot seems to be a German, and controller is Polish. Pilot could not file a flight to arrive to Poznan airport after 8pm, but he already had a hotel reservation over there. Controller was helping to arrange approval for late arrival. I had never heard such long speech on one push of the mike on the frequency. Apparently controller was not busy so he could carry such long conversation.
