The 9 Euro ticket was super easy to buy for me. I bought it in the airport. Not sure why it was so hard for you. I don't speak a single word of German either.
RIP 9€ ticket, you will be sorely missed:/
I'm not trying to be rude, just trying to clarify: Saying that the 9 Euro ticket is easy to buy is like saying a 20 hour flight is comfortable, because you flew Emirates First Class.
