My T randomly charges me more for going over our time but its not like i'm asking to go over. I leave it up to him to keep track of the time. We go over most sessions but its really inconsistent on when he bills me for more. Last session was 15 mins over and he billed me for the extra time. The session before that was 30mins over and he didnt bill me for any extra. I dont get it. Does anyone else's T do this?
