Kentucky Fried ****

Why does KFC always give bad service? I spent more than 30 minutes waiting at a drive through last night just to come out with nothing. After waiting 10 minutes I was informed that there's a 20 minute wait for chicken, which I was fine with as I didn't want to drive any further than that, when I finally get to the window, they close it without saying anything, when I hoot, they tell me to come around, get to the next window and again they close it without saying anything, so I hoot again and again they direct me to come around. When I ask why they close the window, I'm told that it's not a 24 hour drive through, baring in mind that it's not even 22:00, which is the time advertised. Then I go inside and the woman behind the counter is giving the other customer's attitude about it almost 22:00 and also informs them that there's no chicken, so I just wasted an hour just to be told there's no chicken. I request to speak to a manager from whom I enquire why there isn't chicken and he tells me that they can't make chicken until the last minute because what are they supposed to do with the left over chicken, how is that my problem? At this point it was only 21:45
