This summer I took a DB train from Amsterdam to Berlin. Being from the midwest USA, I didn't have a lot of experience with trains so I bought a first class ticket. The air and power in my car weren't working. There was no beverage car or service so we sat sweating to death. After a couple hours they gave in and told us to go to another car. Then at the next stop someone got on and yelled at me because I was in his assigned seat.
