Suspected Mould on Food

We visited walnut grove on 14 June 2015. I usually like to order from that restaurant. Once our food was ordered, i found small spores on my roll which looked like mould. I was utterly disgusted and called the manager. A black guy (I don't what his title was) approached me. Thinking he was the manager, I complained to him and asked questions such as how can they serve food like this, how long do they keep their food, and how can they charge such a high price for food that is old, stale or mould. <br> <br> He was extremely quiet and had no response. Another guy approached me, a white guy, whom I think was really the manager. He argued with me, almost fighting. I had a right to be upset
