I don’t know about Yiddish culture, but there are a lot of cultures where it would be considered extremely improper to tell someone they made a mistake because this would ring shame on them – complaining to a superior even more so. In these cultures, you have to resort to such indirect clues as described in the joke to communicate complaints.
As I understand it, this joke describes the a clash between shame based and guilt based cultures making fun of both.





There is a traditional saying in Germx’an: punctual as the railway. It’s meaning has shifted quite a lot after Deutsche Bahn was transformed from a public service to a private company. So yes, the reliability of DB is indeed incredible. They’d have to issue notes when they’re on time nowadays, though.
