Back in Germany for a sec.
I love countries with great public transit. Because Frankfurt had the hell bombed out of it they were able to put in a subway system, pronounced Oobahn. And it is awesome. You can just go and get on. It’s not like New York where you need a ticket to get on. You do however need to carry a passcard and very occasionally some guys come around and check your passcard. I have no idea why it is such a thrill for me to have my card checked.
It is super fun when these guys get on. The entire car goes quiet. And some people get the hell off, presumably people who do not have passes. It’s entertaining to watch. But occasionally they do catch people. The fine is heavy and they just deduct it from your bank account.
I got controlled twice. It felt so good.
