Returning Yarn To Your LYS??

I'm just curious. What kind of response have you gotten when you had to take yarn back to your LYS?
A friend of mine had a not so good experience at our lys. She did get to exchange her yarn but, she was treated badly in the process. I have only had to return yarn one time, didn't have any problem. Just thought I'd see what other's have encountered in this situation. Also when she exchanged it she spent more on the new yarn and bought more yarn for another project.

only tried it at one of my LYS and had no problem. but they know that they are going to get more money out of me when i show up so they might as well!
