I tried to order using the app and could not get it to work. I went into the restaurant and asked for assistance so I could use the $4.00 coupon. I was told they were too busy to help me and could not use the coupon if the order wasn't placed online. I placed my order with the cashier and no discount. When I got home I received hamburgers and not the cheeseburgers I requested. Not a good experience and poor customer service.
