Jean (nanna) I was working at JoAnn's when the power went out. My other employee that evening was a former bank employee and not a teen. She could not total customer's orders and compute the tax. I put her on the cutting table and ran the register myself. Cash was preferred, but if a customer really needed the fabric and trusted me with me her card numbers, I took them and hand entered the charge when the electricity came back on.
I guess I had better get a treadle operational before the Spring storms start.
