I have known sex workers and they do have their favorite clients. I'm sure therapists feel the same way...just as teachers do, or anyone else. It's human nature to favor some over others.
When we come right down to it, the only person who (hopefully, if we're lucky) loves us unconditionally is Mom. Who else does? Our "favorite teacher" wouldn't be there if s/he wasn't being paid, either. We live, in the western world, in a capitalist society. People get paid to care enough to do their work. Fact.
