Long wait time at the drive thru

On Saturday the 19 July at 2.30 am we arrived at the drive threw place a order at 02.55 and waited another 30 minutes for the order cause the staff decided instead of making enough chicken they will fry each order as it comes in so isn't the point of a drive threw suppose to be a in a out services the entire process took me over a hour how can it be that a big franchise food outlet given this type of services this outlet is busy every weekend so I would expect better planing and services I'm disgusted in the qaulify of food the chicken was half raw.
