Yes, the fats complain a looooot.  Many of them have no appreciation for different kinds of pain too, assuming the feeling of a muscle being tired/fatigued is just as concerning as the pain from stabbing yourself with a butcher knife.  Many are constantly being obstructionist or try to be distracting to kill time and not exercise.  What takes the cake is when they just want passive treatments.  Nope, no need for PT then if that is all they want.  You can just be discharged if you are going to be non-compliant, fatty.
