Counter question: has the manager of a hospital ever performed surgery himself? Has the manager of Ford ever built a car himself? So it's not quite as simple as your question implies. But yes, as a manager, you should at least have a feel for what you are managing.

It is called "public transport" because it is a means of 𝘵𝘳𝘢𝘯𝘴𝘱𝘰𝘳𝘵 𝘧𝘰𝘳 𝘵𝘩𝘦 𝘨𝘦𝘯𝘦𝘳𝘢𝘭 𝘱𝘶𝘣𝘭𝘪𝘤; whether it is free of charge or not is not specified by the term in this case. For further information, please take a look at en.wikipedia.org/wiki/Public_...

PS.: Das sind alles Daten, die bei einer Ticketbuchung abgefragt und an Quantas übermittelt werden. Vermutlich noch mehr. Diese Daten sind nun im Netz, nicht nur, dass du von Singapur nach Perth geflogen bist.

Womit hast du das Flugticket gezahlt? Wann hast du Geburtstag? Schreib bitte auch deine E-Mail-Adresse, Wohnanschrift und Personalausweis- bzw. Reisepassnummer als Antwort hier rein, wenn dich das alles nicht juckt. Dann kannst du die Daten auch mit uns teilen, wenn das kein Problem für dich ist. 😉

This is a prime example of how little companies care about handling personal customer data sensitively. And if the company is fined for data protection violations, the money goes to the state, of course, and not to the victims whose personal data is now public.
