$100 credit and a filter? Man, that guy's cheap. He had them by the balls at that point, with them basically haven stolen his bike. And no way was there implied permission to let another customer take it home, that's nuts. He had those 80 abusive miles put on during the breakin period, causing who knows what kind of damage to the bike, the liability if someone had been hurt on or by it, and he was deprived of its use for a period of time. I would definitely be talking new bike.
