Every fast food restaurant that makes you use a kiosk to order I've found there are interface design problems that make it difficult for a non-frequent user to navigate through. Ordering from a menu and a human cashier is so much easier and faster than these poorly designed kiosks.
The bigger issue though is that the kiosk ticket printer is always out of paper. And -- the kiosk is not designed to recognize when the printer is out of paper, nor inform the employees to restock the paper, nor inform the customer that their order cannot be printed, but the order screen assumes you got your receipt anyway and giving no consideration to the matter, it instantly resets back to the home screen after your order is supposedly finalized, making it so you have no receipt, no record of your order, no order number, no indication at all of whether or not your order was successfully processed. Whoever designed these systems are utter morons. I won't set foot inside a McDonald's or Taco Bell again because of the problems those kiosks have.
