I've actually thought of this. My T does not lock her door, but I wish she had a door that was locked on the outside, but can be opened from the inside. Normally I wouldn't think twice about something crazy like this, but there was one session where she had to reschedule me for 5pm. I'm guessing she does not normally see clients that late. Towards the end of my session, I was upset and had been crying, and all of a sudden there were two quick knocks on the door, then her colleague just walked in. Saw she was with a client, apologized, and left. I did not like that experience at all. Of course, it is my thinking that someone should knock and wait to be invited in, not just knock then open the door. I only assume she doesn't normally see clients that late because I doubt he would have done that if he was used to her seeing people that late.

So I voted no, but wish they did. But I would want it to freely open from the inside, as a lot of doors do.
