Sometimes the locals have to spell things out for the tourists so they don’t freak out about something they’ve never seen before. Squat toilets, intestines on a stick, mosquito nets–all presented without comment or explanation, just read your guidebook to figure it out (okay, except the nice vendor did steer me away from intestines toward a pork satay instead). Which works for me! You’re visiting a culture, after all, so learn a little about it. But I’m guessing the Luang Prabang airport received complaints about its bathroom air fresheners, because they’ve affixed quite the descriptive label to them.
