Macdonalds Drive Through experience

Many of might have experienced really bad service at Macdonalds.. well today was my worse experience. I wanted to get a quick breakfast meal at New Road Macdonalds in Midrand. I ordered my meal and was told to wait for it. I waited over 10 min with no follow up from them. I eventually had to go to drive through window and ask for meal which they forgot about. After another 5 min, they bring only my breakfast wrap and not the complete meal. I then had to wait another 5 min for hasbrown… Total experience at drive through which was suppose to be quick experience turn into sitting at a restaurant and having a meal.
