The worst thing about coming to Fort Mill is this McDonald's. First, it looks like it was built out of spare parts from a torn down warehouse. I've never seen a McDonald's with white vinyl siding, but there's a first time for everything.
The service is awful. One time I went through the drive thru for a cup of coffee and they somehow managed to screw that up. You might ask "how do you mess up a cup of coffee?" The answer is to put five sugars in it instead of three, even though I didn't ask for that many. I don't care if you think it tastes better that way (which is what she told me when I questioned her on it). That's not how I ordered it.
I gave them an extra star because of how terrible their customers must be their employees. They probably get yelled at all day by angry people and it's remarkable that they still choose to come to work.
