It's always been dumb: at best they're just getting more people sick (some of whom will need to take time off, negating any supposed benefit of the sick person not just staying home in the first place), and at worst it's spreading a flu that eventually results in someone dying.
On top of that, a massive number of companies have just proven remote work is possible, even during entirely non-ideal conditions (lockdowns, virtual school, high stress, etc).
I had to explain almost pedantically why they should allow me to order verbally instead of using their touchscreens, for the safety of the other customers.
I think today, they'd have a protocol to accommodate people who are obviously sick so they don't have to touch anything. In fact, they probably don't even let healthy people use touch screens, if I had to guess.
Besides, I would think shooting mucus debris in their direction by talking is worse than using a cleaned knuckle on a screen far away from them.
What are you hoping to gain? And even if you were right, as I said, I had a high fever. It's not like I was thinking clearly. Are you trying to feel morally superior to someone who was in gravely ill?
