    Went up twice and still recieved the wrong order! First time told no receipts for a mobile order my wife placed. Got home recieved someone else's order. Went back. Given the "correct bag" still no receipt. Food looked correct and still missing 4 piece. Get home only to find out I was still missing an entire meal that was ordered. This wouldve been prevented had I gotten a receipt in the first place. This is ridiculous. I normally dont leave reviews but this is store is getting lazy on the evenings/night shift. They're more worried about moving cars out of the window to keep times down that the expeditor isnt checking orders for correctness. You shouldn't cheat window time if you cant get the order right to begin with. I dont know how many times ive been pulled around and got my order with items missing. Store Manager needs to spend some time with the evening shift to figure out the issues. What they have now isnt working. I spent 10 years as a Store Manager and everytime im up there, I'd like to go in and show everyone how to run an efficient shift.

    Garbage location. Really rude and inept workers, have tried this place randomly throughout the years and its always an upsetting disappointment. Management needs to be replaced as they do not make sure their workers are actually doing their jobs.

    I have ordered SF vanilla ice coffee three different visits. The 1st time I ordered I waited and was told we don't have it and waited to be refunded. No apology from the manager. The last two times it tasted terrible. Unable to drink. I just threw it out. Obviously no training on how to make it. I now bypass this lMcD.
