When we arrived at Berlin airport our taxi was not there. We waited half an hour but he still didn't turn up so I called the emergency number and explained what had happened. The person I spoke to was going to call the driver but when he called me back he said that the driver had his phone switched off. I think he may have arranged another driver but he didn't tell me that. Consequently we decided to catch the train, we were on our way to the station when a man rang and said he was our driver so we went back to the airport and finally (1 hour late!) we got our taxi. I was not impressed at all.
