KFC complaint: Extreme food safety failure and terrible service.

Was going to make this food safety complaint directly to our state Health dept. but was told to contact KFC first then follow up with the Health dept.
Sunday, August 15th about 15.30 – 16.00hrs. I ordered at the counter a Chicken burger and large chips. All good, the young male Indian Assistant served the meal as should be. I started to head home and had some chips but noticed how bland they were without any salt on them. I backed tracked to the counter. I politely told the situation to a young female Chinese attendant with glasses. She proceeded to tell a Caucasian female with black hair ( I assume the store manager as she did not turn back to see me). She proceeded to look at the salt shaker and waving her arms a bit, as if to say there is nothing wrong. A new batch of chips had just been cooked , she then THREW MY USED CHIPS BACK IN THE BATCH. MY FINGERS HAD BEEN ALL OVER THE CHIPS BEFORE HAND. THIS IS A HUGE FOOD SAFETY ISSUE ESPECIALY IN THESE UNCERTAIN TIMES. She then made a huge deal and made about 8-10 shakes of the salt, then serves my chips with another at least 4 shakes straight into my serving. It was akin to a childs tantrum. The two assistants were fantastic but the manager was absolutely terrible. I decided to never go back there again but a friend who works in the food industry was mortified and suggested to make this official complaint.
The ball is in your court now KFC. Unhappy customer Peter T.
