Rude manners

We came to kfc kromboom Mowbray to order food, the website showed they close at 11h00pm, literally rushed to them, arrived at the store before 10h30pm, they have no chicken and only select burgers available, requested a zinger burger was told they don't have it available, asked them to drop it but was told they closing at 10h30, told them they can drop it we will wait for it, the cashier called the manager(Zokwanda) had a very rude attitude and barely let us speak finish and just walked away while we still talking to her, she has no manners of dealing with customers
