The first two times (years ago) I went to Lakeside Fibers I was not impressed. (impressed with the yarn, yes) I went as a field trip in my undergraduate days with about 3-4 friends and we would spend hours pouring over the impressive yarn selection only to encounter rude sales people who would either ignore us or talk down to us.
Flash forward to recently, when I was given a pattern I had no idea how to even start yet wanted to complete. I went in and walked around, sort of thought I found the yarn, and then I had to ask for help. What happened next was 3 experienced knitters who also worked there guided me through my selection and counseled me on whether I really needed to buy new needles. They were helpful, friendly, and extremely nice.
The moral of the story: ask for help here, the "may I help you's?" are never going to happen. With that being said, I've been to them all this is the best store for knitters within a 20 mile radius.
