It's issues like this that keep me convinced that doing my own oil changes is a good idea. I know it gets done right, with the oil and filter of my choice. Oil change techs are in a hurry to finish so they can get the next vehicle into the bay. Which leads to the types of mistakes you saw. Which is actually pretty minor. I've heard of much worse mistakes like not replacing the filter, over filling or under filling with oil, and not realizing the old filter gasket didn't come off with the filter. One of my friends at work lost an engine because of the last one, and all his oil leaked out on his drive home.
