The national chains advertise a chassis lube with the oil change ALL THE TIME! They lube the chassis pretty much NEVER!
Took my big Merc in to one for an oil change & lube. I checked the grease fittings before hand & noted the buildup of dust & road grime on top of some grease. If they lube it, the grease will be wiped away & the fitting clean. Got the car back & NOT A SINGLE GREASE FITTING WAS TOUCHED. Brought it back & had them perform the work. I even got an argument about it from the shop manager, "Didn't need a lube, so we didn't do it.". "Do it anyway, I paid for it.". I knew it hadn't been done in about 30000 miles - it needed it.
Another famous rip is to charge for an extra quart of oil. The low price oil change deal is great, but that one extra quart of oil they charge $4 to $8 for. When they did that to me, I asked them to take the extra quart out. "Manual says overfill can damage the engine. Take it out, I don't want it & won't pay for it.". They take it off the bill & send you on your way.
