My T has no waiting room. I have to leave my coat and shoes on the landing outside his office door, and wait there until he buzzes me in. My bus gets me into town 20-25 minutes early, so I usually get a coffee and wait at the coffeeshop in order for me to get to T about five minutes before my session. I like that there is almost no risk at all of meeting anybody else (it has happened, but it's rare) but on the other hand it would be good to be able to get there ten minutes early and sit down and get into therapy mind.
