Wimpy Randridge mall sells stale food

I am so disappointed. I have been going to this Wimpy for close to 15yrs. Today I ordered the special peri peri chicken burger that I have had twice before once at this Wimpy and once at another. The bun came toasted which Wimpy never does. This was already strange. Regardless I knew the waiters so I didn't want to make a fuss and started eating. The chips were stale, I could taste the old oil. I quietly told the manager about this but did not make a big deal. On eating the burger. I could taste the mould. The manager did not approach the kitchen on the chips I saw him on his phone. I then told the waiter about the entire meal and stated that this affects him as the clients will get cross with him over stale food that he has no control over. The onions were old and the chicken had sinew. It was horribly disgusting. Not sure if it's because there is a new manager but sies. I feel ill.
