After many years of toiling in the field I got my business degree and took a promotion to the budgeting office of the purchasing department. The budget was several million dollars a year. Everything went fine for about five years until I made a $21,000 error by not spending that amount out of the capital budget by year end. I admitted the error to the manager who got pissed off and transferred me to a different department and gave the budgeting to a new person.
She came in and made a $492,000 error her first, and last year.
When I heard about the error I bought lunch for the guys.
