LONG WAIT IN DRIVE THROUGH

Today at about 2h30 I entered the drive through of KFC Lenasia South. Waited in an unmoving queue for over 20 minutes , I just wanted to purchase ice cream. 1 measly cone of 4.50 and I'm sure I spent of R30 of petrol in an idling car, of which I eventually switched off. Some people lucky enough to drive small vehicles were able to escape. But I was stuck between a rock and a hard place. When I eventually reached the window to order , I was told I didn't place an order through the intercom! The teller just picked up her mic ear piece and proceeded to take the next order. Second time this happens
