I was on a tour somewhere, I forget where, and the tour guide found out me and a friend were homebrewers. She proceeded to tell us we must not have been very good because homebrewers always ask a lot of questions. Then I asked her if she could explain the metabolic pathways of the house yeast during anaerobic fermentation and to what extent that information played a role in selection of the house yeast. When she stared blankly at me I told her that was why I wasn't asking any questions. I know it was kind of douchey of me but her question was rude and wrong. It warranted an equally rude response.
EPIC. Luckily, the tour guides are pretty knowledgeable here in KC (and the acceptance of homebrewers is quite high). The last time I was on the Unfiltered Tour at Boulevard, the guide deferred some of the tour to me since he recognized me from our club's February competition. By the end of the tour, half of the questions were directed at me. Pretty weird, but kind of cool.
Back on topic... for me, LHBS comes down to two things: availability to order what I want, when I want AND customer service. 'Nuff said.
