Very unhappy customer

Such a terrible experience with staff. This is not the first time. You have to drive through this small drivethru to get to the intercom where they only then put a paper on to say card machine out of order... you cant turn around and have to sit in a long que to just get out. When I ask the lady how else can I be helped she tell me to go find a bank teller and draw money and drive back. I feel the service is not service but just a pay cheque for the employees and if they have problems with card machines (who drives around with cash these days) they can inform customers before driving into the drive through, be stuck and then laughed at!!!
