No Cash Wanted

Tonight I dropped by a local Chinese restaurant to get Carter’s favorite dry sautéed string beans. The girl behind the counter told me the total of the bill and I gave her cash to pay. She looked at the bills as if they were from outer space, “Don’t you have a credit card?”  
I know that using cash is becoming a rare action, but I have never had anyone try and turn in down in person.
“Yes, but I just prefer to use cash and I gave you exact change,” I explained. I was not sure if she was some kind of credit card salesman and was interested in getting me to enroll in some Chinese Restaurant credit card program or if she thought my few dollars were counterfeit. I considered telling her that no one counterfeits ones and that my wrinkled bills were real, but I decided it was not worth getting into with her since she was handing over my green beans.
I like cash. When I buy something with cash I feel it. Paying with a credit card does not have the same effect on me. Yes, I like getting points and rewards, but I really like not having bills at the end of the month better.
I do best dieting if I think of fattening food as high cost food and healthy food as free. For instance a brownie should cost like $20 and an apple would be free. When I think of food this way I do better on making the right choices because I am naturally cheap. The sad thing is that at the real store the healthiest food is often mores expensive that the highly caloric junk. So I have to trick my mind to think that paying more for fruit means I will be paying less when I am hungry. I know this is convoluted, but I have to use every trick in the book to help keep me on track.
I probably would do best if I had to pay for all my food by the bite with coins. Eventually I would tire of shelling money out and would stop eating. Considering my interaction today with just trying to use dollars I am sure that soon coins are going to disappear and I will be stuck with paying on credit cards, or a chip in my arm or some other invention that is going to be the death of cash.
