FWIW, my local LBS replaced a front spoke on my son's bike when we were out for a ride ( some twit in the rack next to him had their quick-release level horizontal and bent his spoke by leaning their bike against his ). They charged $10 for quick in-and-out service in about 15 minutes. But we're very long-time customers and the shop was empty at the time. I expect that if we just randomly showed up at a shop $30 or so would not be out of line.
