tzippi:
ein somchin al haneis only applies to someone who views the events as miraculous. Take R’ Chanina ben Dosa and Rava. Both of them made it rain but Rava was rebuked for being matriach Hashem and R’ Chanina ben Dosa was praised (Taanis 24b). The difference is because to R’ Chanina ben Dosa there is no difference between oil burning or vinegar burning- both are equally miraculous.
