I agree, the staff can be testing at times. I personally have had bad experiences at a LFS
(chain stores not included, different rant) when asking questions. I can tell some of them really know what they're talking about but it's like this BIG secret and I only get bits and pieces of information with a look like I'm a total idiot for even asking. Some of them really don't know what they're talking about and instead of finding out, they just make something up. It can be frustrating which is why I came here to begin with.
I'm sure you will not be that way.
