My sessions never start on time, however I usually get my hours worth. My T seems to have patients back to back. Sometimes she will ask me to give her a minute before she takes me in. I assume this is either because she needs to write something down from the previous client or look over my file, or do some personal business. The key I guess is whether you feel slighted at the end of the session. I don't.Even though sometimes it seems to go too quickly, I usually get my 50-60 minutes of attention.
