Wendy's Old Fashion Hamburgers

I love Wendy's in general. I enjoy their burgers and all the special salads they offer on their menu (like the new almond/berry salad is fantastic!), however, this particular location seems to have a lot of difficulty getting orders right. I ALWAYS order my burger with nothing but a little mustard. My kids order theirs completely plain. Now, granted, it's a request to have something different from a standard burger loaded with all sorts of toppings, but it almost always either comes smothered in mustard, with it dripping out, or it comes fully dressed and has NO mustard. With the kids it's really annoying when they are hungry and we drive away from the drivethru to find that the order isn't right AGAIN. It honestly has happened so many times that I only go back to this location out of desperation - like when the McDonald's across the street was closed due to renovations!
