The local sport club was having a festival on the weekend so several streets were closed. This is the fire department waking everyone up with a loud hailer and siren announcing that any cars still parked here in the next five minutes would be removed, which is something the car adverts don’t show.
The announcement was punctuated by comments like “Attention please. please remove your cars from the Friedrichstrasse. All cars not removed will be towed away in five minutes… Good morning Franziska…”
I’m guessing that wasn’t part of the official announcement.
Even better, on the next street they were making the announcement from a bicycle.*
*Without the bit about Franziska.
