I spend an average of $6 a week (Times 52 weeks = $312) at this restaurant and have always enjoyed the tacos and the friendly service at the drive through. Last Tuesday they failed to add the cheese that I requested and paid for. Today the line at the drive was too long so I went inside to order. I mentioned to the cashier about the missing ingredient and she asked if I had called it in. When I said no she basically said too bad so sad by denying me credit on my order today. So instead of giving me what was due me, 89 cents for the cheese which is really less than 5 cents cost to them they have lost me as a customer and probably anyone else that I tell about this.
