I'm torn on this place. When it's good it's great, but when it's not it's awful. It can be the best chicken ever, but if the oil is old you can taste it and the service is better at you average fast food restaurant.
Like many comments reflect, they treat you more like an inconvenience than a customer and maybe should simply switch to a drive up window if they don't appreciate dealing with the customer service aspect.
Like the Soup Nazi on Seinfeld, it's like they expect you to appreciate paying them for the honor of eating the food, but the food isn't consistently awesome enough to tolerate the attitude.
