Taco Cabana review: drive thru and front counter

Went thru the drive thru and got the wrong order. So we came inside as we were waiting to speak to a manager the other employees were checking our receipt and taking in Spanish not knowing I could understand. They continued to argue with me about my order until i finally stated "I am not going to argue all i want is my food you can te charge me if need be" and they continued to say that was not what i ordered! I am very upset with the way the staff handled this situation i find it very rude to argye back with a paying customer!
