Oliver:

Thanks for your Oslo tip.
You are from MUC - This is my story: I was living in Hamburg and had my office in Starnberg. I needed twice a week a taxi from the (old) airport to/from Starnberg. I never had a taxi driver who could speak fluent German, and never had a taxi driver who was knowing the way in and out of Munich, never. I had to tell them how and where to go: Mittlerer Ring, Autobahn A- so-und-so ...
