I'm trying to figure out if second class means something different in Germany than it does in other European countries or if I just messed up some how buying my tickets out of the ticket machine. As an aside, I only started traveling to Europe around 10 months ago, and this was my second trip, so the latter is quite possible.
A friend and I bought tickets out of a machine at the Munich airport. The second class tickets were half the price of the first class tickets, so we bought those. Once aboard the train, the ticket validator pointed to an area of the ticket and asked a question. I have started to learn German, but I had no idea what she was saying. Our "deer in headlight" looks made her speak in more animated and louder German! This kept going despite my "Ich verstehe nur ein bisschen Deutsch. Sprechen sie Englisch?" Happily, a nearby kind German woman heard my plea and intervened for us. It turns out we needed a Bahn Card for the ticket we purchased. The ticket agent continued talking excitedly in German, punching buttons on her hand-held ticket machine. Finally, she turned to our intercessor, said something with a sigh, and moved on. The nice German lady told us, "She said your story is believable, and it's too complicated to figure out how much you owe, so she isn't going to worry about it." A little shaken (but happy not to be thrown off the train), we settled back to enjoy the German countryside.
So, a good travel story! But not one I'm looking to repeat. I'm hoping someone can answer the "second class means something different vs I screwed up" question as I'll be back in Germany Spring 2016. Thanks.
