I give all the LBS I visit plenty of business because I value their knowledge experience and information and because they have products of quality at competitive prices. I do not stop people from offering me advice after they ask me what kind of bike I have. Before I spend money I do research from multiple sources. I am conscious of LBS time and I am considerate enough not to hold onto someone if I see a paying customer who also needs help.
I resent having to explain myself to someone who had no advice to share. Save your attitude for someone else punk.
