I'll comment on one thing: Memories of being in a rather popular restaurant in Germany. Popular with tourists; many of them Americans......
We were well-familiar with the location of the toilette after a few lagers: down a steep set of stone spiral stairs...across a long, poorly-lit narrow hallway...and back up another set of stairs into the facilities. They were shared with several other establishments and were unisex, but some of the 'stalls' were nicely finished and had glass doors etc... The 'nice' units were normally intended for elders, women, those with kids etc...something obvious to the locals, but not the tourists.
It was always so much fun to watch the 'typical American tourist' when the staff at the restaurant attempted to explain the location of the WC and the amazed looks on the faces of the tourists. "Down there?" "Down those steps?" And then, in the actual toilette, the stunned look (I can think of no other way to put it) when the women and men walked into the common facility. Don't get me wrong, it was all white tile--all white and chrome--with wooden trim. It was hospital-clean in there.
It was always quite difficult not to laugh out loud when the cleaning lady would come in during the eh, 'festivities' and begin to clean while the stunned American at the urinal tried to stammer something in pigeon about 'ocupado' or 'busy' with a bad accent. Not sure why they thought German cleaning staff speak Spanish.... Anyway....it was always a hoot. Not to mention the dirty looks the staff gave the tourist men who were peeing standing-up in the 'nice rooms' instead of using the urinals.
Funny stuff...geography joke I suppose...you had to be there. Hard to see things through different eyes sometimes...
