When I was a retail store business owner some years ago, I preferred cash payments over credit cards because of the transaction fees. I can understand the convenience for the customers to pay with credit cards instead of cash, however, it does seems strange that businesses would prefer them. Personally, I don't usually use credit cards unless it's for a larger purchase (over $100), and I use cash for smaller purchases (ie at farmer's market) because I can physically see how much money I have left...I guess, I am still a bit of old school :)
