McDonalds Montana (zambezi) Pretoria!!! Rude customer service!

So disgusted with the customer service we received today. The place was busy so we used the drive thru. There was a guy standing outside to take our order. We put our order through and my husband requested spicy hot sauce on his burger. So when we got to the window to make payment, he reminded the lady about the spicy hot sauce because usually they forget. So she went to the back to confirm. A guy came to the window and said that the burgers has been made already and they can't do anything. In an EXTREMELY RUDE MANNER!!! Every one else there acknowledged how disgustingly rude that guy was. No customer skills. Pathetic. He did not even bother asking or finding out first. Never supporting that pathetic branch
