Is this not a 24Hour service!?

So I got to the McDonald's Northcliff (Cresta) opposite the BMW dealership. My trip to work timed out just right to make this stop for my lunch later on. Enter the drive through at 5:42am to be asked if my order can be taken. There I was babbling away, only to notice that it was not showing on the screen. Started again \hello? helloo? helooo?". no response. decided to go around to the next window. No one? Stood there for a minute"
