    I have autism ans I went and used the computer to order my food and it didnt give me a number and I didnt see the number before it vanished. The screen that shows that orders are being prepaid was also not working. I was waiting while and I also couldn't remember if I order for here for togo. So there was a tray sitting there and it has 2 sandwiches and 2 hash browns each I ordered. But I added bacon so I thought I would just peek at rhe receipt stuck to the tray. I didnt touch anything and the manager came up and yelled at me to back away.. I was caught off guard and I tryed to explain why I look but he just started yelling at me and I kept saying it was an honest mistake and I asked if he ever made a mistake before. And the morning manager told me no cause his parents raised him right. I was so surprised that the manager was treating a customer that way. I was so embarrassed I just asked for my money back and left in tears. I understand maybe I did something wrong but to just attack a customer like that? It messed with my head.

    Creo que llegué muy tarde para la promoción de 2 Sausage McMuffins por $6 a las 10:30 am, y solo pagué uno. Al llegar a la ventana en el drive thru el muchacho me ofreció un Caramel Frappuccino que le sobró de la orden anterior y mi corazón no pudo con tanto nobleza así que le di solamente lo que tenía de cambio en mi bolso de mano que eran $2.00 pues yo ya había pagado mi McMuffin. Este pequeño gesto me alegró el día bastante!

    Got my order, asked if everything was there and they double checked and said yea. Went home, noticed I was missing an item so I drove back, got the item that was missing and asked if they could double the missing item (10pc nugget). Lead literally said we were busy at that time, they weren’t, and they just can’t give out free food like that. Not me literally driving home and back for this but hey, is what it is. Won’t be coming to this location again. Sad thing is, one of the workers just wanted to resolve it by already having the extra 10pc in hand to give to me and he was literally shot down.
