Subway

I was in that location today and very upset with the customer service. I wound up paying $9 for a subway salad and drink. When I requested to add chips to make it a meal deal and less expensive, he refused to void it and said he had already rung it up. I said I understood he ahd rung it up, but he could void it and start again. He refused and said no at this time he would have to just charge me extra for the chips if I wanted them since he already completed. That is ridiculous and terrible customer service. I told him I would never go there again!
