White Castle

Tonight around 9pm, I went through the drive thru at White Castle and ordered 6 sliders with cheese and a large fry. We waited 15 minutes and someone finally came to the first window and stated "the total will be $29", we proceeded to say that we only ordered 6 sliders and a large fry. The worker stated he only had a order for a crave case. We stated we only had ordered 6 sliders and a large fry. That maybe the car behind us or in front of us orders that. We asked if he could then place our correct order. He stated we had to drive to the back of the like and replace the order in the order.
