Anyway, I’ve been to Memmingen and I liked the Satanic upside-down cross atop the Himmelfahrt church!
I stayed in the FMM Hostel self-service airport accomodation in a former hangar or something, it was cheap and shitty as expected. See my other comment here about what also happened to me on public Wi-Fi during that trip at a train station somewhere between Memmingen and Lindau.

Also, I visited the two-story Kaufland in Ravensburg (the lower level is just parking but whatever) We don’t have such a thing here! I stole a giant LCD clock from their e-waste bin and turns out it worked, it’s in my room to this day.
