Worst service in SA

The McDonald's on Commissioner Street, Johannesburg CBS. Slowest most relaxed McDonald's I've ever been to. U ask them a question they will ignore you like ur a ghost. One lady waited 30 minutes for a donut and when she asked she was ignored like she didn't even exist. I waited 50 minutes for my order and still received the incorrect order. The staff seems to not want their jobs anymore. Why not just resign bcoz wow
