Sad part is cash is expensive to manage in small business. Not only do staff have no cash handling skills, can barely count and have quit under the "pressure" of getting it right, but management have to be constantly auditing the tills. Paying people to incorrectly count is brutal. Plus you have to have a dedicated float that just loses value to fill tills and break bills. Deposits have to be reconciled. Then there is the security of deposits, bank drops and getting coinage. Total pain in the ass.
