Here is the same situation from the point of view of the LBS guy....

LBSguy: Oh crap here comes that dork who shops for a energy bar or a pair of socks every couple of years and then complains about how we don't have the right kind of energy bars or snacks.

"Yes sir...how can I help you today?

rushguy: (looking around the store)

Please don't tell me you don't have any socks...what kind of a bike shop doesn't have socks?
