Taco Cabana review: terrible service

I ordered on line today for food at Taco Cabana. I normally just go through the drive thru to pick up the food. The food was not ready. They told me the manager said I had to go inside to pick up the food instead of using the drive thru.l I am disabled and this is hard for me. I did go inside, my order was not ready. They had trouble finding my order. I just left very angry.
