When I dropped my bike off at the LBS I ticked off a list of things that needed to be attended to, cleaning the chain being one of the items. The guy wrote down on the ticket "major tuneup". I assume that cleaning the chain should then fall under that umbrella. They also redid some cabling so the cost breakdown was $20 parts, $60 labor, $1 tax.
There's some note about adjusting the front fender, which if they did, was pointless because the front fender always gets mucked up when I put the bike in my car to haul it to the shop and back home again.
I still haven't made the phone call yet this morning to find out exactly what was done for the $81. The cables were done. But nothing other than that is obvious to me. The bike was as filthy when I picked it up as when I dropped it off. I had just finished a ride in the rain before I took it in so it was pretty filthy.
