At work, a nurse approached me with a medical gadget with a sticky-note attached that said "Needs New Batteries". She pointed out that it would have been quicker to go to the cupboard, find batteries and replace them than to walk to the office for a note and write it out. She wanted to know the word for someone who would do that.
So what do we call someone who would rather point out a problem than find a solution? Or what would we call that way of thinking?
