Disaster - from the look of the driver's face you know you have made a complete fool of yourself.
The driver informs you that in July 1933 all political parties, apart from the NSDAP were banned & a law against establishing new ones was passed.
Germany had become a one party state.
You panic, open the door of the cab, dive out and say you have forgotten something -- before he can drive you to the nearest police station....
That was a VERY close shave...you will need to be much more careful...You find another cab that takes you to the station without incident.
