This is why in America (and I'm not having a go) they use words like "sidewalk" so you know what to do and where, "wastepaper basket" so you know what to put in it, and over here "Please don't thrown coins in the pond, it poisons the fish" so I can figure that the £30k of Koi floating at the top is worth way more than the coins at the bottom.
You could send each one a personal message, and handwritten letter, an email, phone call and tell them in person marking each gap between the words with a punch in the face (and a full stop in the nuts with a size 10 toe cap) and there WILL be someone who doesn't get it. The bell curve of intelligence works both ways
