And the person might not even need to be there physically, they could just be an image.
Do we need to publicly shame and ostracise employees of all advertising and marketing companies?
All ice-cream manufacturers?
What about smoking? Smoking kills 10 million per year, COVID is a pittance by comparison. Should smokers wear a yellow cigarette badge to distinguish them from others?
1 million die from the effects of second hand smoke - which can come off of clothes, even imperceptibly. Best to know about it, and give them a wide berth. Eg, probably a good idea ban them from going into shops at all. And from buying food, starve them out of the habit, eh?
Do remember here, COVID is NOTHING compared to smoking.
That is, by supporting such measures against COVID and not against smoking or any other preventable cause of death, you're effectively a "murderer".
As such, I'll be giving you and folks like you a wide berth myself, though I wouldn't go as far as restricting your ability to feed yourself.
No need to thank me, it's just common human decency.
