KFC Meyersdal Poor Hygiene

Bough a Zinger & Colonel Burger. While waiting for my order I noticed the staff giving a person that was sitting in a zinger burger. The person opened the burger and touched it and saw that his order was wrong. He informed the lady that it's the wrong burger and she took it back and put that burger in the front where all the take away burgers go. She then opened it, touched it went to the back, fetched a slice of cheese and slapped that onto the burger. She then wanted to give me that burger!! Luckily I noticed all the time what was happening and informed her NO she can't do that. How can you give a burger to someone after it's been touched/handled by two other people??? That is not very hygienic. This is the last time I will ever buy at this outlet. This is the second time picking up issues with this specific outlet. Definitely something wrong at this place with poor service.
