Even if T was going to answer this their answer would be different each client.

As far as my T:
Do they think of their clients after hours? Yes T does!
Are they annoyed to receive phone calls? T keeps phone conversations short. So I don't think T likes the phone.
Do many clients call in crisis? I don't know T returns calls between 4-6
Maybe the clients need to be more considerate of their T's "off" time? My T only work M,W,F until 5 pm.
