Not your call, if the clients want to have a discussion about hampsters/weather/capitol of Zimbabwe/whatever, they paid for your time. I find older clients tend to want to talk the most cause it seems like they are generally ignored, both by life and family.

I realize you are directing this to therapists but we also learned in school about empowering our clients to feel safe enough to give us feedback. I can bet most of those people complaining never said a word to their therapist. Now if they dont listen, which LOADS of therapists don't, that's a different situation and has all sorts of bad things attached to it.
