Slow McDonald's

I just went to the McDonald's in Malibongwe. I wanted to do a drive through, I didn't get any response, then I was told to go inside. I ordered two Breakfast wraps. I waited for more than 10 minutes, I didn't get my order. Another lady came in complaining that she waited for more than 15 minutes for her order. I had to leave without getting my order because I was running late. This is nonsense.
