Just use Cash!

Why do some people use a credit card to pay for low priced items like a $.99 bag of ice? Just use cash! I had to wait for 5 minutes for the man in the check-out line to pay for one bag of ice! It took me less time to buy $44 worth of food. My general rule is: if the total is less than $20 I use cash. It is not that difficult people - get a clue.
