The taxi driver in Erfurt appeared to be in a bad mood. "You have to look up the name of your hotel now? Why didn't you do that on the train?" he asked.
I remained silent. Finally I found the name of my hotel. "Krämerbrücke," I said. "Do you know that hotel?"
"What do you think of me?" he replied. "We are in Erfurt, not in Frankfurt. I don't wear a turban."
Aha, I thought, we are in the former GDR.
But probably that was a prejudice.
