I've seen maybe a handful of my therapist other clients before/after sessions. It's never bothered me. I've referred friends, ex friends, and random people I've met. I remember one person kept saying she wanted her family to see my therapist, and I talk to my therapist, about feeling jealousy toward the adolescent daughter if she took them on. My therapist assured me, if this family saw her, it would not effect how she feels about me, and how she does my therapy. I had to trust her. I've been with my therapist for 14 months, and the other family 9 months. And absolutely, no problems have arisen, even when the friendship broke up4 months ago.
