Most money exists electronically these days. Cash on hand is a liability to the business. It can be stolen, lost, and even if it isn't, it's just sitting there and not making more money. I used to work part time for an armored car company, and it just happened to have the route my own little hometown bank was on. They never got more than $50k a week. There were banks in smaller towns that got $15k, and most of it in bricks of change.
