Performance up on halstead, I'm assuming. There is a pretty wide range of attitudes in there. The store manager is cool, and there are some others, but some of the employees are definitely better than you because they work in a bike shop and you don't. It's not a great place for parts and stuff, though because they have a lot of employees and they all have store discounts they actually do know a crapload about accessories; ask one of the people who has been there a while about lights, and they actually know the pros and cons about all 47 models they sell.

There's no excuse for being rude to customers, but look at it from their point of view. They're the lincoln park bike shop (f*** village cycles, while we're on the subject) and the cheap, mass market option for most of the city. 98% of the people the see don't know their a$$ from their elbow, and it's probably closer to 100% when the topic is fixed and single; most people who know what's up and want that kind of stuff in that neck of the woods go to Yojimbos.

Sadly, they're in my top 5 for shops in Chicago. They've never really done wrong by me, which is more than I can say for pretty much every place besides Yojimbos, Uptown, Boulevard, and Rapid.
