content: I worked as a pizza delivery guy for a short time, and once one of the employees had trouble adding 50 cents to the price total, like he straight up got confused  when trying to add up the tip because the 50 cents was so confusing to him. Many of the employees had trouble with basic math skills. It was a moment like that where I truly realize how amazing it is that we're capable of running a functioning society as well as we do today.
