Poor Customer Service

So got to McDonald's in Auckland car. Drive through, ordered no problem, next window where I had to pay no1 at the window. Waited a bit, no1 came, I moved. To the next window thinking maybe I need to pay at the next window. Got there and I was presented with food, took out my card said to the lady I haven't paid there was no1 there, she apologised and luckily there was no car behind me I drove to the previous window. It was so embarrassing to hear these words from the manager "Yena bekayaphi angaka bhadali" I mean I don't work here I find the window closed with no1 there, the next logic thing that will come to your mind is drive to the next window. I mean I'm the1 who said that I haven't paid, and me being the1 that needed to complain I didn't complain. Disappointing customer experience. Please step up, not all of us coming there are students
