An unhappy customer

I am utterly disgusted by the behaviour from the KFC Epsom Downs shopping centre. They put up a sign that they’ll be open at 08:30am at 8:45 I wanted to buy food. After a 5 minutes back and forth with one of the workers they opened. One of the guys started yelling that they will not sell to us if we wanted breakfast oh wow ! Top tier after buying wings and 2 bucket for ones one the lady disrespected us that we will not be serviced on time. The meat tastes so bad and there are no spices nor is there tomatoe sauce in the take away. May the person who owns the KFC store in Epsom Down please intervene and teach the stuff customer service.
