Pathetic Service, missing food items!!

I went to the drive through at Burger King in Riversands, firstly the store was empty yet they took almost 25 minutes to bring our meal. We ordered two Extra Long Chilli Cheese meals, only one was brought out. We had to wait for the second one, and that took forever as well, we were asked to wait in the parking. As soon as our order arrived we drove off, only to find the Extra Long Chilli Cheese burgers had NO CHEESE!!! The store is empty, why is everything such a mess there? At some point the lady at the payments window asked us not to proceed forward then after 10 minutes of holding traffic asked us to drive to the next window. What an unprofessional fast food place.
