I find it interesting (well, actually, sad) that the author chose that picture for the image of a &quot;public toilet&quot;, instead of, say, anything like here: <a href="https:&#x2F;&#x2F;www.google.com&#x2F;search?tbm=isch&amp;q=지하철+화장실" rel="nofollow">https:&#x2F;&#x2F;www.google.com&#x2F;search?tbm=isch&amp;q=지하철+화장실</a><p>(The query says &quot;subway restroom&quot;)<p>It&#x27;s a classic failure of imagination.  When you live your entire life using (or refusing to use) abysmally dirty public transit system, you kinda assume that it&#x27;s a part of inevitable human nature.  And then of course it stays unchanged, because everybody in the town <i>knows</i> it can&#x27;t be helped so why waste precious budget on it?
