I love it when bad ass cocky roadies stop in the shop. You know the type. The ones that are too cool to pay full price for tubes, riding the latest $5k bike they scored on a shop deal because they work for a large pharmaceutical firm (cough, amgen, cough, cough). The ones that sneer and look down at my shaggy mtb persona. When they tell me about the superhardcore ride they're embarking on I'll say something like, "man, that sounds like a long ride. You need a Dale's Pale Ale for the road?"
That usually trips them up pretty good. Never had one hit me up for it either.
