Re: You want fries with that?

Because throughput. One person is giving their order, one person is paying their order at the first window, one person is being served at the second window. All simultaneously. Ordering and paying at the same window slows down the overal process. There's even McD's where there are 2 ordering stations because that is usually the bit that takes longest nowadays with plastic card payments iso cash.
