If your dealership is like so many others, now that they've done it, you better do it again yourself. You probably just paid for the most expensive chitty wash job you'll ever pay for. Look at the bright side, at least they probably didn't screw anything up since they probably didn't really do the work. 
Remember the only really good HD service departments are the ones you haven't been to. 
Sad, but probably true up to a point. They most likely changed the oil and filter, as evidenced by the seepage from under the oil filter. Highly unlikely they did the rest of the checklist, however. If they had, they would still have the bike while the "tech" tried to find the throttle cables so he could lube and adjust them.
Firechief, I think this is one part of the ownership experience that we all can relate to. I remember letting the dealer do the 500 mile service on my first Harley, and then having my foot slip off the shifter and foot peg on the way home due to the oil blowing out of the primary inspection cover. Since the bike had been sitting at the dealership for a week waiting for this "service", I just called to let them know what assholes they were and then fixed it myself. It became obvious while going back through the checklist that they hadn't done squat other than change the fluids, based on the dry cables and loose fasteners I found. The Harley experience consists of paying too much up front for the bike, paying too much again for the first service, paying the "Harley Tax" to make your new bike run decently, paying a ton for an extended service agreement since you can't trust the reliability of the product, paying top dollar for accessories, etc. The main theme here is "pay".
Do yourself a favor in the future and either do the maintenance yourself or find a good independent you can trust.
