If they use bulk oil from a dispensor gun, someone may have yanked on the dispensor hose while the gun was still firmly inserted. Remove the oil cap and see if there are any sort of witness marks.
Like you, I really don't know what happened. That still should not keep you from returning to the shop and asking if they remember having any difficulty while working on your car. That doesn't mean that you have to insist that they repair it, but just see if they have anything to say.
