what about feigning naivete. i see that happening sometimes. i've seen a guy get bullied and bullied in the workplace and do the work of several other coworkers for a long time. And then one day they needed something really important done, and they had no clue how to do it, though they have been taking credit for his work for like a year, they cozied up to the guy and asked him for help again. he said no that time.
