here in america it depends on situation... example one time when my therapy discussion was on religion my therapist did invite me to attend church services at the same church that she attends and also provide the transportation. I went, we sat together in the same pew incase the service triggered me in any way and then afterwards she gave me a ride home again.

here in america this is perfectly fine thing to do, we checked out the legalities before hand. what it boils down to is any public event like attending church, schools and so on is appropriate for treatment providers and their clients to attend together, or separate and just happen to run into each other outside the therapy room. it happens naturally.

what cant happen is if therapist and client are attending the same public event the therapist can not say to someone else ... this is my client so and so. or bring up anything that is covered by confidentiality.

here in NY there are many small towns and cities where treatment providers do attend the same public events as their clients. heck I went to high school with one of my past treatment providers.

in normal life its normal to be attending the same events as someone else a person knows and be told about this church or that one and be invited to attend. they just have to keep that professional line of confidentiality whether its a teacher inviting students to attend a public event or a doctor or a therapist. or if they happen to run into each other out in the public.
