When I announced our arrival at the reception desk, they said they were full. I had booked rooms for the group but the manager said they were cancelled by phone a few days before. He insisted that he recognized my voice and that I had made the phone call. We had a bit of an argument but they obviously didn’t have enough rooms. In the end the manager phoned other hotels in the town and found rooms for everyone but in four different hotels. By this time, the coach had gone so we had to get taxis and some of the tourists started to get very angry with me. I still don’t know who made that phone call but it definitely wasn’t me.
