KFC staff gives horrible service

Tonight @ 9 I went to KFC drive thru. Where we had to order I waited 10min but there was no one so n drove to the pay window there was also no one waited 5 min then hooted 3 times then the lady came to take my order. Did not say anything I just had to give my order. Then at the collection window there were 3 cars in front of me. Took 20min for them to help him because there was no one. The guy hooted like 10 times. When I got to the window all the staff was standing chatting ignoring me and when my food was ready she just gave it to me and said nothing. This is not the first time that this happened. Nandos was also open. I know they are more expensive but the service there is brilliant and the chicken tastes better.
