Absolutely not, lol; It's the opposite. I have a keychain one that I'm too lazy to remove. And it actually twists and gets caught in the holes on adjacent keys, so it's not like I never notice it!
Because it's implied...? The graphic is based on health experts' advice that people stay at least 1.5 meters apart, not that they stay exactly 1.5 meters apart with weird synchronized movements.
Sorry, I'm doubling-down on my argument! But the real reason is probably because not everyone knows what and mean...
I love science memes, but this is just silly. It's so obviously "at least" 1.5 meters. If you're in this exact formation, you are 1.5m from 2 people... and about 2.12m from the other one.
Cult-like behavior. Literally. "You're with us all the way and must always back anything Dear Leader does or says. If you disagree with anything, you must be kicked out, expelled, recalled, fired, or voted out!" It's absolutely psychotic to view the world in such zero-sum, black/white terms.
I know it's tempting to dismiss these people as all being assholes. But in my experience, once they realize they're in your way, they'll usually apologize and move. Drives me crazy, but some people really are that oblivious.
