We end by scheduling a session for next week. Often that involves him going to sit at his desk to look at his appointment book. Sometimes we hug if it has been a really intense session. Sometimes I tell him thank you if the session has been really helpful to me, he has given a lot of himself, etc. I pay at the beginning of session, so we don't have the money to take care of at the end. When we first met, he requested that we handle the payment that way, because he said it would be less disruptive to what we had just experienced in session.
