Running out of stock

This is a complain about KFC at Platz-am Meer Swakopmund. Every time we go to order our take-aways, there are some items not available! Whether its ice-cream, Pops, wings, patties and yes, even Coke!! Last we went, they were about sold out on everything except chicken pieces. So, you order the chicken meal and cannot even get your sides(like gravy, coleslaw etc) and then they tell you they ran out of chicken and will have to wait at least 40 minutes!! This is unacceptable! Really? its a "FAST" food. I must say that the workers are very friendly
