Folded bikes on German trains

It used to be the case in Germany that when travelling with a folded bike on a German train where there was a charge for bicycle transport that folders needed to be put in a bag. I was once threatened with a bicycle charge for the seven minute journey between Bensheim and Weinheim unless I popped the folded Brompton in its cover. There are Jobsworth everywhere. This is no longer the case and one even sees naked Bromptons on ICEs. Cumbersomes, nonfolding bicycles are an absolute no no these trains.
In many ways the pendulum has now swung too far the other way and full sized folders can be transported free of charge on ICs as long as they are folded. They must however be folded. This is waste of time since some bikes are almost as big folded as unfolded.
