Went to the store today. Some woman had her cart parked in front of the stuff I wanted to get at, talking on the phone to her guy (husband? boyfriend? son?), apparently discussing the purchase, to make sure she got exactly what he wanted. After waiting for her for too long, I went and got some other things and came back to find two other people waiting for her still trying to figure this shit out. So, sometimes you just have to anti-socially undistance and bolger your way right in there, because that damn phone is just a whole nother world to some people.
A friend of mine (who works in construction) has taken to carrying a tape-measure when shopping. Seems to be working for him thus far. 
My sister texted me a pic of an Italian man who had constructed a six-foot (2 meter) radius cardboard exclusion device which he wore about town to enforce distancing. It worked only to attract photographers to him.
Not the best strategy.
I like the tape measure. Much more subtle than my approach, I must admit.
Now I’m picturing some other passive-aggressive asshole who starts to fake-cough back at O.P. until you wind up with two past-middle-age men barking hoarsely at each other in the freezer aisle, while other shoppers give 'em both an alarmed glance and increasingly wide berth.
Bonus points if you also pictured the scene being narrated by Sir David Attenborough. ("The two males have challenged each other for territory, and neither is willing to back down. Although the chances that either one will mate successfully this season are slim, they continue the threat display … ")
You are living in the past, man. Gone are the days where you used to be able to openly cough but had to shamefacedly cover your farts. Quite the opposite now.
Aus is also metric, and we’ve gone with 4 sq meters, which is a 2x2 square (6’6"). But only a 5ft circle (1.5m). Which means I’m allowed to move 1ft either way in the centre of my 2m square 
Our supermarkets are ignoring it, which irritates me a little, mostly because I was already irritated by the way they stack display items out on the floor in order to narrow/pinch/slow traffic and encourage impulse buying.
He’s a Rich Mann and he’s gone too far
But you know it don’t matter anyway
You cannot cough on some old man, sonny!
You cannot cough, just cause your nose ain’t runny!
Did you try using your words? "Excuse me, ma’am, but I’d like to buy some pasta. Could you please move out of the way?
He didn’t say he was coughing on the guy who was standing too close. Just that he was coughing, presumedly into his sleeve, or a handkerchief (maybe even hand-sanitizing afterwards). It’s a little passive-aggressive, but if plain old aggressive isn’t working… I dunno. I don’t think the story is cute either, and I’m not sure what he was expecting when he posted it, but I don’t quite get the hate.
You’re not far Enoooough away!
It’s so Eeeasyyyy to cough on others when you’re insane!
He said:
That–as people who have been arrested for this have found out–is called “making a terroristic threat.” And he really could have it, and been asymptomatic. He deserves every ounce of the hate.
Yeah, this. No one is questioning the desire to have the person give you more space. But it’s a jerk move to use fear to achieve that. Why not just ask the person to step back a little? Why scare everyone around you?
Golf clap.
Admit this wasn’t nearly half as clever as you thought it would be.
Probably more importantly, if he DOES have it, he is spreading it by coughing. Coughing spreads germs around much more efficiently than just breathing, even if you put your mouth in your elbow.
Reminds me of a scene from Newsradio. The office went non-smoking, but Bill (Phil Hartman) pointed out that they were required to have a smoking area, to which Dave agrees. When he asks Bill where the smoking are should be, his response is “A mobile six foot radius around me”.
Problem is, I waited too long, built up too much testosterone in my system. Experience has taught me to go away, because otherwise there will be a scene. If I allow myself to get started, there is a serious risk of escalation.
Hoop skirts may come back into style.
Yeah, well, I say down with home rible assholes, whatever they are.
Meh, I kinda do.
