an anecdote about a waiting room A few years back when I hired a new junior / intern and I had to teach him things, I used this as a visualization helper how linked lists work 😆 after I tried 2-3 times without success he was able to understand properly everything with this example.

And... here we have the same system today too, so it was the same N yrs ago and it's the same now and so annoying when someone is lazy to raise their hands and say "I was the last one" and after 10 minutes we still don't know. Oh and I used the "insert into the list" with the example of an incoming pregnant patient. They never have to be appended to the list at the end.
