In addition to the pathetic and zoo like train services offered for a length of time by the deutsch bahn, what is also happening now is that if one buys something from the shops inside the train stations, chances are if the customer doesnt check properly, the shops could give 10-20 cents less in return money/change. Ive experienced this a couple of times and wondered if this was a new strategy of Bahn to recover the losses theyve been having!
