I did #5 (the embarrassing, not the slapping) to some high school kid in a mall a has been doing some work at. Dude used the original and walked right out. When i came out he was chatting up what looked like a classmate or friend. So I walked by them, close enough to say a quick aside to the girl, and walked on. Pointed directly at him and said “he didn’t wash his hands” and left to the sound of her laughing at him. Or me. Dunno. He wasn’t laughing tho
