That's very disappointing to hear. To be honest with you, when I spoke to Germans on our holiday in September 2018 (Lake Garda.. I .can highly recommend it..absolutely wonderful) I related my experiences. I didn't mention the trains,though.. and just as you've basically said, they said "Its not like that anymore " It was said in a disappointing tone too. They were in their 70's.I was there '73-76. I fitted in well..not least because I learnt to speak, read and write the language at a good level.. (helped having a German girlfriend who didn't speak english..lol) but because of my 'in order' mentality. I like living in a society governed by rules and regs..it makes for a well-ordered society. There was a footbridge I went over each day..over the river Main (Frankfurt) and there was a sign at each end. Translated ...'No cycling'. The only person I ever saw cycle over it was a Brit..from Castleford, West Yorkshire.

One day a German man told him ..shouted at him, to get off the bike..to no avail. Not only did the trains run punctually but the trams.I recall being on a tram into the city centre one day and two youngsters..about 12/13 years old, got on and put their feet on the seat opposite. Wow. They got a mouthful from a male passenger who got off his seat and went to them..have you ever a German being angry..? lol.. and off came their feet and not a word from them. I can't imagine they'd ever do that again. At work each morning the chief technician and his two assistants did the rounds starting at 8.00am....on the dot.
It sounds to me that I wouldn't feel the same now. My nephew's wife is German and they live with their three children in Munich. Small world.
