Yep and sometimes it happens in unexpected places. I just went to the dentist the other day.
The receptionist accidentally moved her task bar to be oriented vertically on the left and couldn't get it back to the horizontal bottom position.
We're on very friendly terms so she asked if I could show her how to fix it which involved going around the desk. Naturally I requested she hides any windows that might violate HIPAA compliance before I swung around.
It was interesting to see her facial expressions and "whoa!" reactions when I mentioned how you can left click and drag the task bar to different spots and how to prevent this from happening in the future by right clicking and locking the task bar.
What was really interesting to me was when I said right click on the mouse, her eyes immediately looked at my hand on the mouse so you can't take left and right clicking as granted knowledge that everyone has as muscle memory.
This is someone who has been using that computer for years to manage appointments and whatever else, but things like right clicking the task bar is a move that very few people do out in the wild unless they are approaching enthusiast levels. She's not out of the loop with tech either. She has a smartphone and does a lot of things with it.
