One approach to react to ridiculous behavior is to simply ask the other person something like "so you're telling me to repeat that I'll be fired if I don't do X". This technique is called mirroring. It's a tacit reminder to the other person that what they're saying is outside the boundary of your immediate comprehension - forcing them to be more conscious of their behavior.
