I recently used the system to order a bunch of chicken nuggets for my four kids. When my order came out, I got a bunch of spicy nuggets. If you have young kids, you know that this is a disaster. Anyway, I said, "Uh, spicy nuggets? That's not what I ordered." The supervisor sighed and immediately said that I could keep them if I wanted to, but he'd fast-track a new order of regular nuggets for me (on the house, of course). Then he started complaining about how the kiosk UI confusingly puts the spicy nuggets as the first choice, so this happens all the time.
Meanwhile, an old man was hollering about how he wanted to pay with cash, but the kiosk wouldn't take cash, so another employee was trying to figure out how to transfer his order to the register at the counter to take his payment.
So in addition to being a horrible experience for customers, this whole thing appeared to be a disaster for the company in terms of both employee time and real money.
