I frequent this Five Guys fairly often, and normally have a good experience. Today was the third time I'd ordered through the app, and my experience was nothing like I've had before. I hope it's a fluke, but just in case. I waited 15 minutes for my order after I arrived to pick it up, even though I checked in right when I arrived, and all the while I watched order by order of those who had come after me be called out. Once all the orders were gone, I asked if mine got missed. The girl behind the counter, who was noticeably flustered, asked what number it was. I told her I ordered through the app. She looked around and found my ready made burger sitting in a bag on the shelf, seemingly forgotten. I also had ordered a milkshake, which they made fairly quick after asking twice what add-ins I wanted (something that was clearly printed on the order ticket). Again I hope this is just a fluke.
