Not so better than cash

So I'm making a purchase at a little shop. The bill comes to $10.27. I hand the clerk my Visa card because it gives me miles. He swipes the card into his card reader and stares at the cash register. Then he describes the Visa commercial where a guy uses cash and the world stops behind him. He goes on to tell me what a crock he thinks it is because he constantly has to keep his customers waiting while his machine connects. The conversation goes on for at least two more minutes before the receipt is printed rendering Visa's commercial totally ineffective for him and me.

Now in fairness, I'm sure it was not Visa's fault. It's probably the fault of the transaction processor, time of day or what ever. But, most people would blame Visa. Most won't stop using it though if they get miles.
