Retailers do track spend based on payment type. It was the case several years ago that people who paid with credit cards tended to spend more and buy higher margin items than other payment types. I'm not sure if this is still the case, but if it is, then that is one situations where accepting credit cards pays for itself. It is helpful to keep in mind that different businesses can pay wildly different fees for CC transactions. Walmart can sell you a $0.50 item for basically nothing, while a corner market might be better off if you stole it instead. So Walmart might absolutely want everyone to use credit cards while the corner market would likely prefer nobody did.
