Bike store employees are such a mixed bag. Half the time I get unhelpful pedants, the other half they're great and go beyond the call of duty.

But here's a tip, if a guy asks a question, it's because he wants to learn and likely doesn't spend all his free time studying the cycling product market. There's no reason to be a jerk about it. Nobody likes the pedantic IT admin, and nobody likes the superior bike shop clerk.
