I found an entry from my time in Colombia last year, that got lost in the shuffle of research. I likely was waiting for two other items things to add to the list, as the previous posts included multiple curiosities. It felt greedy to not share this with you, since I had enjoyed it so much. Here it is, a year belatedly:
I was walking home from work when I passed a bus with underoo seat covers.
I walked past it twice, then asked the driver to explain it to me. He talked in great detail, politely, about the benefits of leaving the edge of the headrest without a cover, asked me what I thought, allowed me to take photos of his luxury bus.
