@lopcute Not only in Berlin there was a wall but all along the border. On my bicycle trips I have seen that wall everywhere, after 1989 it came down and now only this type of signs remain (from my 2012 trip Baltic states)
The tram driver just made an announcement asking whoever was eating Chinese food to please close their takeaway box. “It smells really bad up here in the driver’s seat.” 😂 #OnlyInBerlin
