Touch screen McDonald's

I ate at McDonald's today, something that doesn't happen all that often. So I was surprised how far technology had come in that place. They had touch screens there now, where I could place my order, pay with a credit card, get a receipt, and go with that receipt to the counter, where somebody was already filling my tray with my order. That went a lot faster than the usual dialogue with the person at the counter, especially when the restaurant is crowded and loud. Good idea!
