Drive Thru Terrible

We are regular visitors to this branch (at least twice a week) and the person taking the orders at the drive thru is always the same person who accepts the payment. When you get to the payment window that person is most times taking the next order and doesn't even have the time to look up at the client who is handing over cash or card. Last night when we got to the payment window the next customers bill was added to ours and when we mentioned it we didnt even get an apology. The service was very good before, but you have just lost regular clients
