After I had solved a ticket from Rostock to Zossen...

After I had solved a ticket from Rostock to Zossen for myself and my labrador, Lars, and asked when buying tickets in the DB Travel Center whether there were specially allocated areas for dogs, this was negated. Halfway up the bus, the apparently bad-tempered driver pointed out to me in a brief break in Oranienburg that I had no right to stay here with the dog. When I replied that I had asked for extra, he asked me irritably if I had not read the terms and conditions. When I said no, he snapped at me: Muzzle! After I kindly pointed out that I could also have been pointed out (eg when buying tickets !!!!), He told me that he had the next time the right to refer me of the train! He then went into his cabin and slammed the door of his "driver's cab." Do not worry, dear train, next time there will certainly be NO.
