Paying restaurants in cash instead of credit card - how signficant is this?
The biggest advantage to small business owners paid in cash is not that it might save the 2 or 3 percent that would go to the credit card company.  The biggest advantage is that they have the opportunity to keep the transaction entirely off the books and pocket the cash without paying income tax or sales tax, especially when no receipt is given, or when it's a service instead of a product being sold, or when it's an approximately-tracked inventory unit going out the door.  Although it's illegal, it's widely done, and it's also often a temptation for employees to try and get away with doing it too.
