Sonic Drive-In

Got home to find II had sliders instead of cheeseburgers and called the manager. He told me I ordered sliders and I told him I ordered double cheeseburgers (like the ad on tv) He told me he took the order and I ordered sliders. Told him I was not going to argue with him, but I would never be back (never got to the "hard as rocks tater tots). At my age (over 70) I would not order sliders for dinner (have never had a slider before) What happened to helping the customer?
