Depends on the girl and the session. Sometimes I've gotten a continued backrub after, sometimes a nice snuggle, and sometimes a "here's your hat, what's your hurry" as I was herded to the door to make room for the next client.
As for MSOG, the only time it was offered I was too relaxed by the massage to take advantage of it. The flag pole was up, but the 21 gun salute wasn't going to happen that day.
