^ Agree. See if they also check the bottom bracket to crank interface and check the bottom bracket tightness. This service should be ~ 45 minutes of work tops. Some shops also clean the bike by wiping down quickly, but in my mind this is the owner's responsiblity.

Disclaimer, though. I don't bring my bikes to shops, I've just read and heard when visiting shops to buy the odd part or tube...
