This is how my LYS has treated me every time I've gone in there.
I don't know if it's intentional, but with younger people in the store she treats them very poorly. With me, my friend that was with me, and there was another lady that came in. The lys lady was helping her pick out yarn colors, and flipped out on the girl because she took too many colors out, or messed the order or whatever and the lys lady got all pissy and said she was going to have to redo it now.
Then, one of her older friends came in and it was just completely different.
I really have never had a good experience there. Unfortunately, that's one of the two available in the area. And the other one is further away, and I've never been there.
I keep meaning to. I've heard they have mostly just novelty yarn though.
Oh...and, uh, on a topic related note... I've never returned yarn to my lys.
(Mostly because I hardly buy anything there.)
