I wonder if anyone could inform me how to handle this situation if it arises again.
I had my ugliest train experience in Switzerland, on the 18 minute train ride from Lauterbrunnen to Interlaken. This train line is not SBB and so not offer free rides, but does give a 25% discount with the pass. I bought two paper tickets - which would have been about 7 chf each but were discounted to 5 chf or so. So I saved 2 chf using the pass.
A conductor questioned me about it - and wanted to see the QR code for the pass. Since the train trip does not even appear in the rail planner, I had no idea how I could generate a ticket. This was further compounded by having no internet access. I am not sure if I could have added it manually or what to do.
This conductor was almost yelling at us like she had caught some criminals sneaking on the train, and demanding we go with her to the office at the terminus. This then entailed nearly an hour of my time. At one point I went over to the grocery store across the plaza to get wifi to pull up the pass. They would not give me any wifi access in the station.
Eventually we did not have to pay the additional 2 chf per ticket, and the guy in the office said we just need to generate any ticket for the day to make a QR code - even if its not the same trip. Is that true?
