I recently had the oil changed on our '93 Camry at the local gas
station/garage that I have been using for 20 years and has been there
for probably 40 years.  Well respected neighborhood business, never
had a problem before.  I decided to wait since they said they could
do it right away.  As I was watching, the mechanic/service person was
having trouble getting the old filter off.  Finally got a pair of
giant slip lock pliers to try, it was then that I noticed he was
turning it the wrong way.  He would have figured it out eventually
even if I hadn't mentioned it.  Later he had his associate start the
engine to run the oil through and check for leaks.  Trouble was he
hadn't put the new oil in yet.  I also mentioned that.

Point of story:  you can have poor work done in every possible
situation, Cheapy Quick places, dealers, local stations.  I really
don't think that one is necessarily any better than another.  And
experience can not always be the guide, as in my case, 20 years good
experience!

Whoever said that the only way to get it done right was to do it
yourself was right... I'm sure none of us has ever made a mistake in
our auto repair/servicing, eh?
