In high school I worked at an ice cream shop. My boss would not let us use the register to determine change. It was the best thing that miserable jerk taught us.

Same. Worked at a snack shop at a ball diamond from 10 years old to 15 (ahhhh - child labor) with no registers or calculators of any kind. The calculators started popping up about the time I left (this was 30 years ago).

It was fun at other jobs when the electricity was out
..I was the only on able to make change. Or teaching a student years later how to make change for the lottery sales because there was no register.
