Waiting on food

I went to Kentucky in Plumstead to grab a bite to eat. I ordered a Streetwise 2 and and crunch burger. My order was taken without incident but i waited for twenty minutes for it to arrive. I checked the time on the slip and the time i collected my order. I was not told that there would be a delay and there was only three customers waiting with me. I then left but had to go back to buy something for my partner. I used the drive through this time and was told that my streetwise 2 would take 8 minutes and was asked to wait on the side. My order eventually arrived after 15 minutes. To make matters worst i asked for a drumstick and thigh but received a breast. I wonder if KFC undertand the concept of fast food.
