When I lived in Cleveland I came across countless people who ran most of their business in cash. One was an Italian restaurant that only had 3 employees on their books. Here in West Virginia, we have personal property tax. So the state eventually gets its money when you buy something with your illicit cash.
Not if it “falls off the back of a truck”.
The local Chinese Restaurant in my Cleveland Neighborhood only uses the cash register during lunch. They stop using it at 5 pm. It is only used for credit card transactions.
