I live in Atlanta and I can honestly say in the 30 years I have been eating there, I have NEVER ONCE recieved the wrong order.  Never once have I ever recieved attitude or the feeling that I was bothering them by wanting food (looking at you McDicks). I have ALWAYS felt like they were genuinely happy that i came in and I always leave satisfied. The service is always top notch.  Also the food is second to none.
