In Episode VII: The Force Awakens Rey makes her first attempt to use a Jedi 'mind trick' on the stormtrooper sent to guard her.
When the stormtrooper is right beside her she makes another attempt by saying
You will remove these restraints and leave this cell with the door open
the stormtrooper replies
I’ll tighten those restraints, scavenger scum
Now, we have seen what happens when a Jedi Mind Trick doesn't work but I was wondering, was the stormtrooper trying to be funny or can Jedi 'mind tricks' actually cause the affected person to do the opposite of what a Jedi says?
