It depends on what you have done. Sure, to adjust cables and tighten the handful of nuts and bolts goes quick and they might slide by for $20 - considering statistics prove you'll buy some accessories or something else while you're there. That's where the real "gravy" is - impulse buying. A new bag, a pair of water bottles, some of their sponsored energy bars, etc.
Now, if you're going to do a REAL overhaul - including disassembly, cleaning, and repacking, for both wheel bearings and headset and BB, plus truing the wheels, and oiling and adjusting all working components, that ain't going to be done for $20.
