It's not unheard of for lube techs to forget to drain the oil in the first place.
I would not be surprised if your engine had double the amt. of required oil after it left the shop when the oil was changed.

As mentioned above, all of that "check check check" stuff never happens.

Your lucky if they actually change the oil filter and refill with the correct amt. of oil + tire rotation. Many shops only have ONE wt. of oil in the service area. Whatever that wt. is - you get. Don't be surprised after a dealer visit to find the pressure in your tires to be all over the place and lug nut torque whacky as well.

While it may seem like a small thing, you may be charged for the oil pan gasket - part # 90430-12031 and never actually get it. Old gasket reused.

I know people live in places that don't allow owner servicing, but if you don't, change your own oil.
