as long as they seem healthy and taken care of I dont think there is much of a basis for asking them to change. I know some of the stores dont do very well at that but when I was in the local store recently there was a young guy picking some up and asking the guy there some questions, mostly on what kind they were. The man working the store seemed knowledgeable, I made sure to stay nearby to see what he had to say. I talked with him a bit and told him what I thought they were. They were just labled layers and surely looked like sex links and the straight run were RIR. This guy at least seemed to know his stuff. I also talked to the young man on his way out just to be sure he knew what to do and the man at the store certainly told him correctly.
