KFC Stormvoël | Yet another terrible experience

Good afternoon, Once again we had a terrible experience at KFC Stormvoël in Pretoria. We arrived on Saturday 24 August just before 11 and proceeded to the drive through queue, of which we were then the 3rd car from the front...not having any idea of how long this was going to take. Our order was placed and the time reflecting on the slip was 22:59:31. I have 2 further photos, showing that at 23:20 we were still in the queue, having to hear once we at last got to the front, that there was no chicken. Really? This constantly happens at this specific KFC. When will they learn that communication is key? Put a board or staff member where the queue must start, and tell people what the issue is. Once you enter a drive through you can impossibly exit, not even for an emergency. Should it not be our choice whether we want to wait 20+ minutes for a meal, at a drive through! People hooting and shouting and a manager who just looks at one but doesn't come speak to us even when requested to do so??? This is not the first time this has happened at this specific branch. Perhaps they should order, prep and make more chicken, seeing that KFC is a chicken outlet??? Further...are manager's not supposed to be people who are trained in assisting customers, whether they are difficult or not? Shouldn't a manager stand up on behalf of a company and apologize, not turn their back and refuse to speak to clients? We requested our money back and left...and still have had no KFC. What a disappointment of an end to an evening. Just wanted to bring this under your attention, as I see so many people have tried to do on Hello Peter, Facebook and other social media pages.
