I had a work colleague who had a spreadsheet with one column calculating something to do with a particular date. They didn't have any formulas at all. For any calculations. They would go in each day and manually calculate and then type in the values. In every cell.

I put in an input cell date, and simplest of formulas in 3 cells, and they looked at me like I was some kind of wizard.

I returned to my desk, put my head in my hands in sheer shock. I still don't understand what they thought a spreadsheet was for....It made.nice columns?

Anyways, when I recovered, I finished my resignation letter,.and that was the best thing I ever did in that particular cesspool 😁
