I worked in groceries story when I was younger.
But funily enough, it’s probably one of the rare times I’d have answered “yes”!
We got a policy here where anything mislabelled under 10$ is free for the first item. Anything over 10$ gets a 10$ rebate.
My understanding is that it was put in place a while ago when stores stopped labelling individual items to keep them in check and ensure that consumers had a recourse in case of mistake.

NULL being “no money” by any definition, and the regular price for this probably being under 10$… well, it’s probably free!
I agree with the sentiment of your post, but I think the examples are a bit too far fetched:
I’d wager most people use a computer/phone on a daily basis, which is why having a basic understanding of it seems like knowledge we should all have.
Inversely, most people don’t need even have a turbo in their car and many don’t even have a car, so any knowledge relating to that is probably useless for them.
That being said, even if someone is less knowledgeable in a field, respect should always be the baseline, as you illustrate, they’re probably skilled in something else!
I’m saying that as an IT person that’s aware that I’m making money mostly because people don’t bother to learn all this, so in the end I don’t mind that much.
