Each day when I buy goods pay with cash always. I don't have a credit card so I don't know how to use a credit card. Because this reason, I prefer to use cash rather than credit cards. For me, cash very easy to use. When the state of emergency if there is cash it's better than a credit card, because I can pick the cash out to pay immediate. If one day I have a credit card and I try to use it I can compare the differences between credit cards and cash
