Sings ain't vot zey use do be.
You book a bavarian train seat. They tell you the carriage number and the seat number, they even tell you how far along the platform to stand so that your carriage will stop right in front of you. Such efficiency!
But while you're standing on the platform in your allotted spot, the PA yells out: they've had to leave out half the carriages, including yours. The shortened train's at the other end of the platform.
Mad scamper with luggage. You hear another passenger cursing the bavarian railways, apparently things used to be better. I'm not going to make a cheap joke about the Auschwitz trains.
