Kfc Randfontein worst services ever

Yesterday night,I tried buying some Kfc via the drive through. No 1 not all tellers Windows are used,so you can only order and receive your food at the last window.. I waited about 40min,the line never moved. During that time I decided let me rather park and go inside,as I now needed to use the bathroom. Went in used the self service, went to the toilet,the doors was locked. Approached the counter ask if I can use the bathroom. Was told by the manager named Gugulethu no,it a kfc policy that no toilets to be used by customers after 10pm. Like what but you sell us food for 24hrs. Our monies are welcome for 24hrs,but not all service are available 24hrs
