KFC review: poor service. manager didn't show consign. I feel like a fool

First when I got there I went Drive thru they didn't answer ‘Drive thru suppose to be fast' why it called drive thru but they are busy in there making jokes and not working. So after the drive thru been slow I went inside to place order and it took me additional 10min before someone came to take my order if only I knew how to take orders I could have taken it my self to fasten up the process. So when he came he even has the ghost to start having attitude, I asked for senior discount he can't give me my senior discount, I ask for sources he said I have to pay. After placing my order he in there making jokes and he using his hands without gloves to make my sandwich and I am on break I have to go back to work . The service there really really sucks I'm sorry to use that word and pls improve y'all management thank you!
