Hey, I do get that bidets aren’t culturally well established everywhere, and even in bidet areas they don’t often come with detailed instructions, so usage habits are kinda random.
But that’s why I went to the shower bit instead. I would hope cleaning your nethers when you shower is a universal habit, or at least as much of one as washing your hands after a trip to the toilet.
But hey, maybe permanently sweaty, poopy undercarriages are just… you know, “an American thing”? I don’t know.
I mean, the lit-up signs are for visibility. In some countries pharmacies are assigned strict working hours by the government, so it’s useful to see at a glance if a pharmacy is currently open without having to walk right up to the door (and night shifts may require ringing a bell in some of them, so that’s also helpful to convey that they are in fact open).
The fancy animations are just because when signs went from neon-lit to LEDs it turned out not all pharmacists have good design sensibilities. At least as far as I can tell.
