In my misspent youth, I worked for a large recreational pharmaceutical manufacturer and distributor. My focus was in the accounts receivable department. The first time I heated the knife's tip to red hot was while collecting unsold merchandise and funds from sold merchandise that one of our sales reps decided to keep for himself. Luckily he complied before I followed through with having his eyeball meet the tip of the knife. I'm glad I never went down that particular dark path, I have enough demons that still haunt me.
