Why would a restaurant offer a very large cash discount?
Another possible reason for this is to benefit the servers. When patrons pay with a credit card, they usually tip on the credit card too. If patrons are more likely to pay with cash, then the servers will get more cash tips. Even if the restaurant is completely honest with their books, the servers may not be. Having a restaurant where tips are mostly cash might attract better servers, or perhaps enable the owner to pay servers slightly less than otherwise.
