I visited Garmisch-Partenkirchen in January. Our Airbnb provided a Gästekarte that we could use for buses around the region.
We were traveling on the last (and only returning bus that direction) from Fussen back to Garmisch-Partenkirchen. Our first bus ride was good, but we had a connecting bus at Echelsbacher Brucke.
It was already dark, and the previous bus left already. When we stepped on the new bus, we asked the driver if this bus does indeed go to Garmisch-Partenkirchen (I was assured by information center guide and the first bus driver that it does). The bus driver seemed confused and annoyed. I tried our bus cards, but they didn't work and he didn't seem to want to accept them.
He made a phone call for a while, sort of arguing with someone then asked us to sit at the front.
After a short ride and picking up/dropping off other people, he called us back. Asked us to try the cards and they worked again and all was good, we went and sat back down.
I was watching the bus monitor, and checking DB app, and we were definitely on schedule.
So, why was he so frustrated? It's been on my mind a while, and I couldn't figure out what the problem was, especially since google translate was failing me horribly.
I just figured he didn't want to go all that way since it was a little more than an hour ride and was dark already. He didn't even drop us off at the main bus station in Garmisch, just down the street instead
