BAD SERVICE- FOOD WE EAT NOT SAFE for us to eat

A very bad service I got from KFC Canalwalk. Went to buy a box master they give me a box muster with no tomato no lettuce. When I complain the manager told me to bring it back not even an apology. People don't understand the importance of the food we eat and show no respect. I never ever buy from them again and will make sure my friends and family don't, even the people I work with were shocked.
