Drive Thru frustration (KFC Bloubergstrand- Service Road)

I have been to this Blouberg KFC twice already, and every time I go through the Drive Thru, they tell me it’s not working, no sign to indicate that, and it’s really frustrating how they practically make you drive through and you’re unable to order, the second time I asked the lady to atleast put a sign or a traffic cone to show people that it’s not working and she just left noted me and was more rude
